[gentoo-user] USB printer and new cups

[gentoo-user] USB printer and new cups

[Alex Schuster]

Hi there!

I want to setup an USB printer. So I http://localhost:631/, and notice 
that the interface has changed. And when I try to add a printer, the only 
options for a local printer are SCSI-printer and HAL printing backend. And 
on the next screen, I have to enter the device URI by hand. How should I 
know what to enter there? And wasn't there an autodetect feature? Is the 
new CUPS (1.4.3) generally behaving like this lately, or is something 
wrong with my setup?

The usb use flag is set. lsusb shows the printer as "Bus 001 Device 003: 
ID 04a9:10a5 Canon, Inc. iP5200".

What is a HAL printing backend? Do I have to add some crazy fdi stuff for 
the printer? CUPS does not even have a hal use flag. Dale, help!

Did you ever get this printer working with this particular gentoo 
installation?  If not have you seen this page:

http://en.gentoo-wiki.com/wiki/Canon_Pixma_Series

They make suggestions for drivers that may work.  CUPs requires that you have 
installed the correct drivers for your device first.  Sorry I can't help more.  
Last time I tried to get a canon working was more than 5 years ago and I 
couldn't find a driver or ppd info at the time.

HTH.

Well I have a HP.  I had trouble the other day, read that as the printer 
was turned off and I didn't know it, so I deleted the printer.  That was 
when I realized it was turned off, so I turned it back on and hplip or 
something just added the printer without me doing anything.  KDE showed 
a little pop up and it was done and it has printed ever since.  This 
could be habit forming tho.  ;-)  I like things that "just work".

Do you have ppds and dbus USE flag enabled for cups?  As far as I know, 
that is all I enabled for mine.  Just for reference, this is my USE flags:

USE="X avahi dbus gnutls java jpeg ldap pam perl png ppds python ssl 
tiff zeroconf -acl -kerberos -php -samba -slp -static -xinetd"

The two I mentioned above is the main ones I would guess.   Most of mine 
are global flags.

I hope you see something to at least try.

Hm.  Glad you brought the subject up because I just noticed that I no longer
need the ntfs useflag.  I once had an MS Windows partition for those very rare
occasions when I was forced to run a Windows application, but now I can use
wine or VirtualBox to run any Windows software that my banker/broker/city/state/
federal government may coerce me into using.

Alex:  when I plug in my HP USB printer, I see this in dmesg:

usb 2-2: new full speed USB device using uhci_hcd and address 2
usb 2-2: New USB device found, idVendor=03f0, idProduct=1617

Do you see somethinhg different?

I never used an USB printer at all. But I installed a lot of network 
printers, and one local parallel printer. I could select the device in the 
web frontend then, it had stuff like 'LPT #1' or 'USB Printer #1' in the 
device menu.

The Gentoo Printing Howto has this:

  USB Printer #1   Select this when the printer is locally attached to a
                   USB port. The printer name should automatically be
                   appended to the device name.

But I see no USB printer here.

Thanks, this made me install gutenprint which claims to support the 
printer directly. I thought I had to use the iP4200 driver and hope it 
would work. 

But my main problem is another one: How do I tell CUPS which device my 
printer is? I tried usb:/dev/usb/lp0 (found this notation when googling 
'usb printer device uri'), but nothing happens when I try to print.

And now it gets really crazy: In the printer overview I see not only the 
'iP5200' I just created, but also a 'iP52002' that has the device URI 
'usb://Canon/iP5200'. What did create this?!

But printing to that does not work either.

That's not the global USE flags, just the ones turned on for cups.  I 
ran emerge -vp cups and then copied the USE flags from that.  This is my 
global USE flags:

I suspect that a lot of those are no longer valid tho.  I need to clean

will show the dead ones.  I can't recall at the moment.  Oh well.

That was my first impression also, but those are only the USE flags for 
cups. Mine are a little different, but I have another cups version (Dale 
does not even seem have a usb USE flag):

USE="X acl dbus java jpeg ldap linguas_de pam perl php png python samba 
slp ssl tiff usb -debug -gnutls -kerberos -static -xinetd)

Less verbose, but similar:
usb 1-2: new high speed USB device using ehci_hcd and address 3
usblp0: USB Bidirectional printer dev 3 if 0 alt 0 proto 2 vid 0x04A9 pid 
0x10A5
usbcore: registered new interface driver usblp

There is a message in syslog that is being repeated hundreds of times:
May 15 22:25:55 [kernel] usb 1-2: usbfs: interface 0 claimed by usblp 
while 'usb' sets config #1
                - Last output repeated 58 times -

I noticed that but my cups version does not appear to even use the usb 
USE flag.  It's not enabled, but it is not disabled either.  I do have 
usb enabled globally tho.  Strange but my printer works fine.

This made me think, hplip is not running anymore.  This is weird.  
Printers on this time too.  lol

A stab in the dark:

Does udev know about the printer? - this identifies a new usb device to
the kernel as a usb printer instead of just an unknown usb device.

Do you have sane installed? - if its a multifunction device sane may
have grabbed it first (for the scanner) locking the printer out.
Requires some manual tuning of the udev rules if this is the case (this
is required by my epson multifunction)

I think that gutenprint is the correct driver for your printer and this page 
also suggests the same:

http://www.openprinting.org/printer/Canon/Canon-iP4000

However, this might have been the case before the latest cups version - so 
some further testing will be required (see below).

This is the cups driver (in kernel) which ought to pick up your usb printer 
and use it without problems.  However, according to your logs ... there seems 
to be a clash:

> There is a message in syslog that is being repeated hundreds of times:

So, what happens if you build usblp as a module and you modprobe -rv ubslp?  
Does cups pick up your printer now?

I suspect that this was created by the gutenprint driver that you installed.  
I believe that if you resolve the usblp error first then you'll know if 
gutenprint is necessary or if it will work.  Some manual tweaking of the ppd 
file may also be needed to print in higher resolutions, but let's get it to 
print first.

Stop press!

I just checked again your first post: You are using cups 1.4 which accesses 
raw usb devices!  Definitely remove usblp (or blacklist it and reboot if you 
don't want to recompile your kernel, or can't modprobe -r) and see if the cups 
back end picks up your printer on its own.

And I just found this:

I was too busy to try this. And I don't have the printer here right now. 
But I will try this soon, so thanks.

Thanks Mick! I will try again soon, this time on another Gentoo machine, 
where the printer finally belongs. I just wanted to try it out and to 
check the printing results. Well, this did not work at all, but at least I 
know now that it should be supported, while before I was under the 
impression I had to use a similar driver, and hope for good results.

just remove the usblp module (blacklist it or remove it completely
from the kernel, if its already a module, modprobe -r it) and restart
cups. Cups uses raw usb devices. It should appear at the web
interface.

with cups loaded and printer connected:

# /usr/libexec/cups/backend/usb
direct usb://Kyocera/FS-1010 (...)
       ^ cups device URI
