usb printer problems

[Ben Paley]

Hello,

I'm having difficulty with usb devices, specifically a camera and a printer -  
I'm starting to tear my hair out!

Problem ONE is that they are not always detected. Sometimes everything goes 
fine:



ugen0: Eastman Kodak Company KODAK EasyShare DX4530 Zoom Digital Camera, rev 
2.0
0/1.00, addr 3



and



umass0: EPSON USB2.0 MFP, rev 2.00/1.00, addr 2
ulpt0: EPSON USB2.0 MFP, rev 2.00/1.00, addr 2, iclass 8/6
ulpt0: using bi-directional mode
da0 at umass-sim0 bus 0 target 0 lun 0
da0: EPSON Stylus Storage 1.00 Removable Direct Access SCSI-2 device
da0: 1.000MB/s transfers
da0: Attempt to query device size failed: NOT READY, Medium not present
(da0:umass-sim0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0

(da0:umass-sim0:0:0:0): Medium not present

(da0:umass-sim0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da0:umass-sim0:0:0:0): CAM Status: SCSI Status Error
(da0:umass-sim0:0:0:0): SCSI Status: Check Condition

(da0:umass-sim0:0:0:0): Medium not present
(da0:umass-sim0:0:0:0): Unretryable error
Opened disk da0 - 6



(all the da0 stuff is to do with a built-in multi card-reader) and all the 
right device nodes are created for the printer - /dev/ulpt0 and /dev/unlpt0.

Sometimes these messages don't show up, but I get this a few minutes after I 
turn one of them on:



uhub0: device problem, disabling port 2



Or something like it, depending on where I've plugged it in.

I am really not sure what's making the difference, except that it seems never 
to work if either of them is on when the box boots up, or if I turn on the 
printer before the camera... but those are certainly not the full story, and 
I can't pretend to have been exhaustive in testing all the permutations.

Problem TWO is with the printer, a nice new Epson Stylus Photo R300, which 
works beautifully in Windows. In FreeBSD, the camera works fine (with gphoto2 
in the command line) once it's detected. But the printer responds very 
poorly. Doing



su-2.05b# lptest 20 10  /dev/ulpt0



makes the printer kind of clear its throat, like it's getting ready to do 
something, but changes its mind. I've tried sending a line feed afterwards, 
and pressing all the buttons on the printer, and none of those things seems 
to help. The machine is supposed to accept US ASCII plain text, according to 
linuxprinting.org. At least I know I've got the right node, as redirecting 
to /dev/unlpt0 does nothing at all.

Although it seems futile to go further before I've sorted this out, I have 
tried some spooling stuff. Apsfilter, of course, and there's a proper driver 
for this printer, print/pips-spr300_310. I've installed that and followed all 
the setup instructions, configured /etc/printcap with the supplied script...



su-2.05b# lptest 20 10 | lpr -Pspr300_310
su-2.05b# lpq -Pspr300_310

Rank   Owner  Job  Files Total Size
1stroot   0(standard input)  210 bytes



But nothing will happen at all, for ever, not even a throat-clearing. One 
thing I haven't tried is editing usbd.conf - is there any point doing that in 
this circumstance?



su-2.05b# uname -a
FreeBSD potato.hogsedge.net 5.3-STABLE FreeBSD 5.3-STABLE #0: Thu Oct 28 
14:12:12 BST 2004 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/POTATO  
i386



Here's a bit of dmesg.today:



uhci0: VIA 83C572 USB controller port 0xd000-0xd01f irq 10 at device 4.2 on

and here's a bit of my kernel conf:

Printer problems

[Stephen Montgomery-Smith]

I have a HP Deskjet 932C.  I was having problems with printing out large
douments - right in the middle of the print job the job would stop.  lpq
would complain that the printer was offline.  The only fix I found was
to reboot the computer.

I fixed the problem by switching to using polling mode (using
lptcontrol).

Is this a known bug with the lpt drivers?

What mode is your parallel port in?  You might want to try
experimenting with the various PPT modes, ECP, ECP/EPP, and normal. 
With my printer, I was having problems with the PPT mode set to ECP/EPP
and EPP, but the problems went away when I set the mode to either ECP
or normal.

Actually, I don't think this is the case with your printer, but I
thought I would give it a shot.  I think it's a thing with the HP
printers that they seem to not work very well unless you use polling.

Re: printer problems using 3.4RC kernel

[Mike Smith]

You're not clear about what you're printing, where you're printing it to, 
or what the actual output looks like, but these symptoms are entirely 
consistent with you trying to print plain text or some other encoding to 
the printer.  You need to ensure that you're actually printing to the 
correct printer device.


 Hello everyone,
 
 I've just finished cvsup'ing 3.3-stable, to bring my 3.3-Release system up 
 to date.  Everything went fine and seems to be working except for my laser
 jet printer.  Its a NEC SuperScript 870 which emulates to a HPLJ IIP.  The
 printer gets recognized fine during bootup and everthing appears to be OK
 until I try to send roughly more than 1 page of data to it.  The page can 
 be sent by cat 'filename' | lpr, using a2ps, or just dumping from a
 webpage with html, it doesn't seem to matter.  What happens is I only get
 a small amout of data on each page, and then the next page is sucked into
 the printer and again only a small amount of data is placed on it.  I am
 using apsfilter as the printers textfilter.
 
 I compared my boot logs with the new kernel to the GENERIC 3.3R kernel I
 was using previously, and there isn't a bit of difference in them.  All I
 did was eliminate devices that weren't getting found anyways.  I'm sure it
 has to do with the kernel, or its config, as if I boot off my old GENERIC
 kernel my printer functions properly.
 
 The one thing I've noticed is when the printer is working correctly, there
 is significantly more delay from when I send the printjob to the printer,
 and when it starts printing.  Booting off of the kernel I compiled, there
 is almost no delay between when I tell the system to print, and when the
 printer starts to suck in the paper and print out small portions of what
 it should be printing spread out over many pages.
 
 If anyone else is seeing this problem and has any ideas, I would love to
 hear them.
 
 thank you,
 
 Roger
