I spoke to Till (Ubuntu's printing stack expert and all round Linux
printing guru) off list and he as replied to Barry directly.

In the interests of sharing the knowledge this is what he had to say:




Hi,

this is something which often happens. You have a printer which is newer
than the Ubuntu version which you are using.

HP is releasing new versions of HPLIP (HP Linux Imaging and Printing) more
or less every two months (on http://hplipopensource.com/) and we are
putting the newest version before Feature Freeze into each release of
Ubuntu.

On http://hplipopensource.com/ you can look up whether your printer is
supported by the most current HPLIP version. Independent of this, HP's
printers (or their communications protocols) do not change much between
generations, so often the driver for an older model works.

Which printer model did you select to make your printer work?

Do not report a bug on CUPS. CUPS is not supposed to deliver drivers for
new printers.

   Till



Cheers, Will

[ubuntu-uk] Printer problem ...

[Barry Drake]

Hi there    I've just installed my printer on xenial.  The printer I 
have, is missing from the database in cups.  I had to get the driver 
from HP.  The printer is an HP Deskjet 30558 all in one.  Is this 
something I should report as a CUPS bug, or is it an HP problem that I 
need to report there?  Any suggestions please?  Obviously my printer is 
working just fine now.


Regards,Barry.

I realised last night that if your problem was caused by an update, it 
could only have been part of CUPS.  Looking through Ubuntu web archives, 
someone with 10.04 did have a problem with a CUPS update.  Not quite the 
same problem though.  My wife is still on 10.04 and has a stand-alone 
printer.  Also she had not done an update for a few months, so this 
morning I ran all the updates except for CUPS and then checked the 
printer before updating CUPS (4 updates) one update at a time.  All 
done, and sadly for you, no problem.


I think my final suggestion is to back up absolutely everything, and do 
a complete install from scratch using the current 11.10 Oneiric Ocelot.  
I know this is a pain, but without access to your computer, I don't 
think any of us are going to get any further with the problem.  It just 
is not repeatable on other equipment.  Make sure you back up the printer 
driver and if needs be, I'll talk you through the printer installation 
again.  Sorry to seem unhelpful.


God bless,Barry.

I've had a posting off-list from Michael, and replied as follows.  Does 
this make sense?

I followed the thread, and like all the others, am at a loss.  When you
said 'update', I did wonder if you meant 'upgrade' to 11.10.  I can't
remember where you began - I seem to think it was Natty - 11.04 when we
spoke on Skype back in September.  Upgrades are almost guaranteed to
throw you out of kilter.  If you did an upgrade, you will almost
certainly need to re-install after backing up all data.  I re-install
every six months now using the latest release.  Obviously it means
re-installing your printer afresh, but first prepare to be delighted if
your printer is found and installed automatically.  This happens with
hardware and new releases.

It could be that completely un-installing and re-installing your printer
(automatically) might fix the problem.  I have a suspicion that this
might be the case if you did an upgrade, as Ubuntu could have
re-installed the printer on upgrade.

There is normally no such thing as a print authentication password -
passwords are only asked when you try to use something installed by
another user - and an upgrade would have been carried out by 'root' as
you gave permission for it to do so when you ran the upgrade if that
were the case.

My suggestion when all else fails: struggle on until April when 12.04 is
released.  DON'T upgrade to it; just re-install.  When your printer is
installed to your new 12.04, it will work as before.  Obviously all your
data will get lost in the re-installation, but you will have it all
carefully backed up somewhere (won't you?).

Glad to hear your health is improving.

God bless,Barry.

HI Michael,

The access control is what I was thinking of when I last replied (from 
my phone, so I couldn't see the settings).

Try turning the access control setting to deny everyone, add your user 
to the white list and try again. Then try setting it back to allow 
everyone and delete your user from the list. See if either of those 
help with the problem.

Ahh, I've also just noticed on the Policies tab (I'm using 11.04, so it 
might be slightly different), there's an Operation Policy setting, 
which has the values Default behaviour and Authenticated - mine is 
set to Default, so check yours isn't set to Authenticated.

HTH
Neil.

Exactly what does it say when you try to print, and when does it say
it in the printing sequence?

[ubuntu-uk] printer problem

[allen williams]

After running update manager two days ago, and rebooting as instructed, my  
printer (Epson RX620) is no longer recognized. The system claims it is not  
connected (which the printer is, via an USB port, which I have changed  
twice). I have also tried rebooting with the printer disconnected and then  
switching it on, as well as rebooting with the printer connected and  
already switched on. It is not out of ink and it carries out its  
independent functions correctly. It seems to be a hell of a coincidence if  
the printer has gone faulty at this reboot. Has anyone any ideas or  
suggestions - gratefully received - ?

[ubuntu-uk] printer problem

[Norman Silverstone]

The printer in question, an HP P1505n, is connected to a router by a
cable as is a laptop running Ubuntu 10.04. Several months ago the
printer was set up and working using the laptop and, in addition, was
working wirelessly with a desktop machine running Windows XP Pro and
wirelessly with another desktop machine running Ubuntu 9.10. A few weeks
ago both of the Ubuntu machines would not print files and, despite
trying all the tests I can find, I have been unable to sort out how to
put things right. Two days ago I set up another desktop machine running
Windows XP Pro which is happily printing files wirelessly.

Please, can someone suggest how to troubleshoot this problem.

Can your Windows machine still see the printer?

I mean, if you open up Windows Explorer and type in \\ubuntuboxhostname 
(replacing ubuntuboxhostname for the name of your Ubuntu  machine) does 
it list the printer amongst any folder shares?

I'm just wondering if for some reason the smb.conf file might have been 
altered and your printer share removed?

I will have a look at that. When this problem first arose, many moons

and this sorted things out. However, this time I cannot find a file

You should find smb.conf in /etc/samba

To edit it, open up a terminal and then enter the following on the  
command line:

sudo gedit /etc/samba/smb.conf

Hope this helps.

It seems to me that the first thing to do after loading a new release is
to go through all the settings etc. to see what has changed and what the
