subject:"\[Bug 35638\] Re\: Printer is not detected properly over USB"

Hi. I'll try this off the launchpad bug forum since I'm not at all sure it will
work for you and don't want to spread any nonsense further than required.
I'm dracon on the launchpad and I was able to get past my cups problem bu
forcing a printer ID.

Here is what you might try. At least it's easy and worth a shot.
Go to System/Administration/Printing click the New Printer button to add a new
printer...Don't mess with your normal set up just leave well enough alone there.

When you get the available printers selection pane select Other
and in the URI field put the exact ID of your cable (copy/paste). From your
note that would be:

hal:///org/freedesktop/Hal/devices/usb_device_4b8_5_M01P20511302159560_if0_printer_noserial
Click forward and select the appropriate device driver for your printer, and
continue to set the new printer up normally..new name and human description,
but leave the default location alone.

This should add a new printer presence named (Different-Name?) to your
printer list.

Try printing to that printer, make it default, see if it is able to reconnect.
This worked for me with a legacy HP4 that cups found about 50% of the time..Now
it doesn't fail and I can recover print jobs if the printer is unplugged and re
plugged.

If this works please let me know. Maybe we can point the Cups/Hal folks
to a particular problem or give some bypass suggestionto the bug forum.
(if it does not work le me know that too)

2008-04-20 Thread quixote

I tried setting up a new printer, R220-test, with the URI as suggested.
Otherwise, same driver, etc.  It worked, I made it default, printed
again, then suspended.

When I came back from suspend, the old Stylus-R220 definition was
working fine and the new default R220-test was unplugged !

$lsusb
Bus 002 Device 001: ID :  
Bus 001 Device 003: ID 04b8:0005 Seiko Epson Corp. Stylus Printer
Bus 001 Device 001: ID :  

Running that command did not make R220-test become functional.

I then made the old Stylus-220 definition the default again, and re-
suspended.

Then both R220-test and Stylus-R220 come up as unplugged.  lsusb shows
nothing on Bus001 or 002. But just running that command makes both
R220-test and Stylus-R220 work.

Re: [Bug 35638] Re: Printer is not detected properly over USB

Sorry bout the goose chase.. seemed to work for me so I thought I'd pass it 
along..(messed up the launchpad in the bargain...my bad!.CUPS is a puzzle I 
think is still missing a piece or two..your experience is strange and different 
than mine so I have no ideas left. Sorry. If I think of something I'll email it 
but really have no idea. Now I am running Gutsy and I think you said you are on 
Hardy..so maybe there is a difference there, dunno. Got me stumped.
Good luck,

Hi Bill,

I found something similar(?)
hal:///org/freedesktop/Hal/devices/usb_device_67b_2305_noserial_if0_printer_noserial
BUT this works for me and leaves a ID Name of Laserjet_4 BUT no way is the
URI the same...I could not fined that length of URI anywhere ... The printer
works; is all I'm interested in now, how to help others is a guess at best,
I have not seen the issues you have in dropping when rebooting, and till I
replaced the Cable, I could not find the printer at all; how do you address
that issue? One other thing is We Both have a Laserjet 4 shouldn't the URI
be the same or very similar, for the same product? OR if it is JUST the
Cable we should be the same also...duh...Or am I not seeing something? In
either case we are forcing the LINUX to pass the identifier for the printer
to be recognized. (just like the issue in Windows I needed to select USB
then windows could find the printer)...

I have been printing yesterday and today the Laptop has been turned on and
off everything works.

I other thing when I sent your the WubI Ubuntu 8.04 Hardy Heron web
site...DO it before you unload your windows. I just install it to my other
IBM laptop R51. It installs and leaves a choice to your BOOT ID (you pick
windows or Ubuntu at boot. BUT the big thing is it acts as complete
installation and creates a vurital disk does NOT affect your Hard disk at
all, and leaves Ubuntu name in the Control panel ADD and REMOVE files. NOW
being installed it finds and accepts your total system, printer, laptop keys
and lights your eithernet and or your wireless, video card, any USB stuff
you have. SO you know even before the offical installating where any issues
are THAT IS COOL...IF you have a 3d Nvida or ATI card you will see the WOW
gnome package, also...

Good luck with the Launch Pad effort, how you handle that is (?) but try
anyway, I guess. Then load the program to check your system with Hardy
Heron. Be aware it has only one site in the USA so a little slow, maybe wait
till tonight to try...I have Warner Cable pretty good in the 500mbs download
range.

Re: [Bug 35638] Re: Printer is not detected properly over USB

George, that is the hal ID for your adapter cable.. that is what I put
into the URI field for the other printer and it forced my HP4 to lock
in..no problems dropping since. If your problem returns you might try
that but if it's working now I'd let sleeping dogs lie. Could be some
cables are weaker than others (electrically not as well shielded maybe?
and some just fail at some point. All's well thst ends..

[Bug 35638] Re: Printer is not detected properly over USB

2008-04-12 Thread Sitsofe Wheeler

dracon:
The thing is, this bug is about has nothing to do with hal (if you read earlier 
comments like 
https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/35638/comments/77 you 
will even see me saying the output of the hal backend is fine for me) or 
parallel - usb cables. I don't doubt that the end result looks the same but 
the cause is different. Really it's about (Brother) printers with broken (built 
into the printer) USB implementations. CUPS only recently (around Gutsy era) 
gained a hal backend and I first filed this issue back in the Dapper days 
(which pre-dates the hal backend by at least a year).

CUPS's USB backend has nothing to do with hal. I do not know what CUPS
currently uses its hal backend for (perhaps to save on polling or
announce the arrival of new printers to interested programs) but I
believe in your case it is a red herring. The hal backend might well not
be working for you but from what has been said I don't think this is
your real problem (as the hal patches are apparently not even carried by
upstream cups). If you REALLY want to talk to the developers of the hal
cups backend you can try the project Utopia list (
http://mail.gnome.org/mailman/listinfo/utopia-list ) but if you do that
I'd make absolutely sure that the real problem is the CUPS hal backend
and not something else. Personally I think you will learn more by filing
a new bug on
http://cups.org/login.php?PAGE=/str.php?U0+P0+S-2+C0+I0+E0+M10+Q and
carefully (but concisely) explaining the issue you have and seeing what
the response is even if it is we won't spend more time on such cables
or printers that use them.

The fact that Windows works just suggests it identifies printers a
different way (without depending entirely on deviceid strings). Maybe it
ties up a port entirely but that discussion would be really better off
in a separate bug report as any discussion here will only confuse people
as to the purpose of this bug report (bugs.launchpad.net isn't suited to
forum discussions).

[Bug 35638] Re: Printer is not detected properly over USB

2008-04-12 Thread dracon

Sure, but it's not a HP issue IMO. Several threads exist with this problem with 
various Printers from Brother as in this thread, to Epson, to HP...on the web 
in various Linux distros including more than this one for ubuntu. Does not 
appear to be printer manufacturer specific, but related to the adapter cable 
handling by hal. If I find a way to raise it as a hal bug in correctly handling 
the usb adapter cables, which is what it appears to be, I'll post that back 
here.
BTW do you know how cups references/uses hal when trying to locate printers? 
and do you have a contact with the hal owners?

Use a parallel centronics printer cable with your R51. It works perfect for
both windows (any)  and Linux (any)
I don't have a parallel in port on my new T61, so have to use USB.  Still
haven't heard about any Cups fixes to solve the USB problem with early HP
Laserjets.

 From above:
 On my R51 connected to the Laserjet4 running WindowsXP, I had to tell
 Windows to use the USB port to find the Printer, it does that and works.
 That could be a way to fix it with Linux CUPS.

 I have same condition except:
 Windows 2K, processor self assembled (INTELD865PERL MB/1.5GB)
 LJ4 on Parallel to USB cable
 HP 890c Deskjet on same cable type.

 My Ubuntu system is Gutsy. (7.10)

 HP 890c never (well almost never) fails to identify and jobs will follow
 it if usb cable is moved to another usb port.
 HP LJ4 almost never identifies.

 W2k is rock solid on both printers using these cables so the cables must
 be passing device ids. Up to now Ive not found many things Windoze can do
 the Ubuntu could not. This appears to be one of those more noticeable
 problems.
 Sometimes a reboot will find the HP4 but usually not. Once found it can be
 added and functions until a reboot.
 Have never seen it drop once found until the system is rebooted. Then it
 will show in the installed printers list but will not print.

 If this is a bug that has been opened  www.cups.org can you point me to
 the bug report and I'll follow it there.
 Thanks,
 Bill

[Bug 35638] Re: Printer is not detected properly over USB

Thanks, but I have the parallel port reserved and have used these
printers several years on Windoze with this connectionneed to use
them via the usb cables and it allows easy unplug and attach to my
laptop. Also problem is obviously not electrical since Windoze correctly
senses and accesses the printers.

Also am beginning to think this problem is not a CUPs problem but a HAL problem.
When the printers are shown available, hal has correctly found both. When  the 
HP4 is dropped (can happen to the 890c but infrequently) hal only shows the 
cable but not the attached usb device. 

If hal finds the HP4 it is listed as an unknown device on usb 1, which
still lets me configure it properly. On reboot, if hal finds the
unknown printer (HP4) on another usb port,  cups reroutes the pended
print jobs to it (cups finds the printer unknown and uses the correct
driver to print a pended document).

hal-device-manager displays the parallel to usb cable correctly and printer as 
unknown usb when it finds it.
When it does not find it, it displays the cable correctly but no usb unknown. 

Suspect this could be a timing problem within hal, occasionally not
receiving a signal back from the 'unknown' printer a startup within the
expected time during device identification. Timing differences withing
the devices themselves could account for the differences in how
frequently they are dropped.

Is there a way to slow the hal startup or cycle process, or re run hal
after the system is stable to rebuild the tables ,or even force a device
into hal's table? (are there any control parameters for hal that can be
user set or forced?)

Re: [Bug 35638] Re: Printer is not detected properly over USB

The problem is, HP Laserjets do NOT have the capability of sending the
correct signal to cups via the usb connection. That is why M$ makes YOU pick
the USB to start with. The HP Laserjets are so old and so few are still in
use that why bother. The problem lies with the early HP Laserjets not having
the capability to announce itself.
Someone must pressure the Cups team to let the Linux user send to signal to
the Laserjet, if you can get that done fine. I just don't think there is
such a need in todays market to do it.

I'm going to try Bluetooth, If that does not work will get a newer printer.
There are switch boxes that you can get for Parallel Centronics cables to
connect to more then one printer. I've seen some of them with 6 switches,
just turn the switch to the printer.

Good luck, It will be interesting to see if you can get the Cups to make the
change at this late.

[Bug 35638] Re: Printer is not detected properly over USB

George, thanks.

Since telling Windoze where the printer is was a one time deal, that isn't a 
problem on that side. Wish that could be done for Ubuntu. 
Parallel cables don't solve my problem of easily switching the printer off to 
my laptop either which has no Centronics port.

Now to cups. I don't think this is really a cups problem but I don't yet
really understand well the relationship between hal and cups. I'm under
the impression that hal runs before cups. It seems that when hal has
found and identified the devices' that exist (even if the identification
is unknown usb device) then cups is capable 1) of allowing  driver to
be assigned to that device/hal port and 2) follow that device if it is
subsequently moved to another usb port between reboots.

It's only when hal only finds the printer cable (Centronics parallel to
usb cable device) and does not find a printer on the end of the cable
(even a  unknown printer) that cups does not present that printer for
configuration in the add Printer options.  That leads me to conclude
that cups is ok but hal is not.

Now I don't know what hal uses to get the hardware info but from what
I've read hal is pretty low level stuff looking for signals on specific
pins with certain timings...etc. Since hal has found the Cable device I
expect that his timing is PDQ and he doesn't wait a long time for the
end point (printer) of the cable to post a signalJust guessing here
but if hal moves on to the next port before whatever device is on the
end of that cable sends a i'm here!, he will not even find a unknown
device and assumes that no device exists. At that point cups can't find
a printer to configure since hal tells him there is no device on the
cable.

Net: I believe this could be a simple timing fix in hal for a coder to
cause hal to wait a millisecond or so for the device at the cable end to
post if he finds a Parallel2usb Printer cable device on the port (he
can tell the difference), (but not me! unless I get sufficently bugged
to go back to school -lol- not likely)

 I don't think this is a cups problem...(is problem for me though)  If
it's hal this problem will be distribution independent across Linuxes
and while the older HP laserjets may be older there are a bunch out
there, and this has more to do with how hal is handling the Parallel
Printer Cable device regardless of manufacturer.. (I lose my HP 890c
inkjet sometimes as well the same exact way...just not as often probably
because it is quicker at responding to it's interface...and I've seen
the problem expressed with Brother, Epson, and other printers of both
technologies in several fora, not just this one. (most end with a null
answer as this one seems to have))

Any idea how to get a hal type to take a look at this? I guess Ubuntu
team could champion it but the interest seems low even from the cups
side. Still if Ubuntu is trying to establish itself in the laptop market
where parallel ports are appearing less frequently maybe they should
take a look at this.

You said you have Thinkpad R51 That has a 25 pin parallel port on he back,
and your LaserJet4 printer has a Centronics port.

[Bug 35638] Re: Printer is not detected properly over USB

George,
Nope. Sorry for the confusion, but I quoted a previous post (who had said they 
had a R51..may have been you) and said I had the same problem, which I do. I 
id'ed the problem with my user assembled desktop with a INTELS865PERL 
motherboard. It has a Parallel port that I have reserved. The laptop is my 
daughter's and it does not have a para/port. Don't have the Make/model handy at 
the moment but when she comes over (frequently) she attaches the printer for 
outputhense the usb adapter cable. It's not uinreasonable to want this 
hardware to work and the HP4 is a horse of a printer with a great engine. Not 
getting rid of that beauty anytime soon.
Anyway, this combination ought to work in LINUX. Muffing around the problem by 
rearranging hardware doesn't really address the issue of the adapter cable 
support deficiency.
Thanks for the responses.

I'm trying to find a way to get to the hal folks to see if they can help
with the issue. There are several threads out there with various
descriptions of this issue and most have no clue where the genesis of
the problem is. If it's not hal it below that level. I really do not
think it is cups but that it is were the low level hardware detection is
occurringSince the cable itself is being correctly identified as a
printer, it seems probable that a timing change in the logic would be
all that is required to fix this.

Wish I knew more about linux internals (only in a brief weak moment, then I get 
a beer and think about the beach)
If I find an answer I'll post it back here..Hope you don't have to buy another 
printer to get this fixed. That is not exactly what I would call a it just 
works solution.
Later, 
Bill

Re: [Bug 35638] Re: Printer is not detected properly over USB

I see your problem, remember it is the printer talking to the computer, Hall
has nothing to do with that. It's an old printer trying to connect to on a
new(er) computer. There must a reason for the cups people to put time into
that setup. If it happens great if not you will need to try another means,
ie a network print server for any computer on that network.
I HAD A R51 and have replaced it with a T61 just recently. Nobody uses
printer ports now all are USB. The going backwards is the problem you need
to solve. The R51 has a parallel printer port.
good luck

[Bug 35638] Re: Printer is not detected properly over USB

Thanks George. Appreciate your input.
Still, it is the same hardware talking to the same other hardware whether Linux 
or W$ and it works every time with W$ the problem has to be SMOP. (Simple 
Matter Of Programming) ... not hardware.
My understanding is hal senses the hardware and determines the device 
infois that not correct? (senses = probing the HW connections) DOesn't cuos 
use input from hal to build it's tables of available printers...
If hal cannot find the printer (finds and IDs the cable ok) then cups has no 
chance to set the printer up. 
Don't really think the printer is trying: to send anything until it's asked.
If it is hal that is asking...and hal leaves before getting the HW answer back 
...viola no printer.
I still believe that hal leaves before the printer gets back to it after being 
polled...
I have been wrong before though...
Time for another beer. 
I'll let you know what I find.
You know it can't be brain surgery if Gates can figure it out...;D

2008-04-10 Thread dracon

Have this identical problem but being a nube have no real clue how to
address.

From above:
On my R51 connected to the Laserjet4 running WindowsXP, I had to tell
Windows to use the USB port to find the Printer, it does that and works.
That could be a way to fix it with Linux CUPS.

I have same condition except:
Windows 2K, processor self assembled (INTELD865PERL MB/1.5GB)
LJ4 on Parallel to USB cable
HP 890c Deskjet on same cable type.

My Ubuntu system is Gutsy. (7.10)

HP 890c never (well almost never) fails to identify and jobs will follow it if 
usb cable is moved to another usb port.
HP LJ4 almost never identifies.

W2k is rock solid on both printers using these cables so the cables must be

Ubuntu could not. This appears to be one of those more noticeable problems.
Sometimes a reboot will find the HP4 but usually not. Once found it can be

George, can you do

sudo usb_printerid /dev/usb/lp0

and post the output here?

Please note also that your problem is not the problem originally
reported here. Your problem is that CUJPS cannot cope with a USB printer
which does not supply its device ID. Every native USB printer supplies
its ID but your adapter cable is a bad implementation, it does not pass
on the device ID which the printer supplies to its parallel port. Please
report a separate bug on this, perhaps even better directly upstream at
http://www.cups.org/ (problem will occur the same way if you are using
another Linux distribution than Ubuntu or Mac OS X).

Hi Till,
here is the results:
[EMAIL PROTECTED]:~$ sudo usb_printerid /dev/usb/lp0
[sudo] password for gpw:
Error: Input/output error: GET_DEVICE_ID on '/dev/usb/lp0'
[EMAIL PROTECTED]:~$

You are correct as I have always used a Parallel Cable with my LaserJet4. If
I used a Bluetooth adapter to the Parallel port on the LaserJet, do you
think that would work? This T61 is the first computer I have owned that did
NOT have a parallel Port connection.

I apologize for your trouble, I didn't mean to get you side tracked like
that.  Thanks for helping me.

On my R51 connected to the Laserjet4 running WindowsXP, I had to tell
Windows to use the USB port to find the Printer, it does that and works.
That could be a way to fix it with Linux CUPS.

Good luck on the Hardy release, really working great, had a little problem
with the network manager step stairs Icon desipearing from the top panel.
The network itself was fine just the Icon in the top panel. It's all fine
now. I did have some early crashes with Tomboy but those are all fine now.
Just loaded SongBird yesterday, slick program, a true Windows Killer and I
might say OSX also...


Thanks again...

[Bug 35638] Re: Printer is not detected properly over USB

2008-03-30 Thread Till Kamppeter

If you do

/usr/lib/cups/backend/usb

or

/usr/lib/cups/backend/hp

repeatedly, are the results always exactly the same?

[Bug 35638] Re: Printer is not detected properly over USB

2008-03-30 Thread Till Kamppeter

George, for me it looks like that your computer is not discovering your
printer at all. Is it turned on? Is it a USB printer? Is the cable OK?

Can you do

sudo lsusb
sudo lsusb -vvv
dmesg
ls -l /dev/usb/lp* /dev/usblp*

and post the output here?
