Re: [gentoo-user] USB printer and new cups
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. with cups loaded and printer connected: # /usr/libexec/cups/backend/usb direct usb://Kyocera/FS-1010 (...) ^ cups device URI
Re: [gentoo-user] USB printer and new cups
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. -- Daniel da Veiga

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: May 15 22:25:55 [kernel] usb 1-2: usbfs: interface 0 claimed by usblp while 'usb' sets config #1 And I just found this: May 15 22:17:40 [kernel] usb 1-2: new high speed USB device using ehci_hcd and address 3 May 15 22:17:41 [kernel] usblp0: USB Bidirectional printer dev 3 if 0 alt 0 proto 2 vid 0x04A9 pid 0x10A5 May 15 22:17:41 [kernel] usbcore: registered new interface driver usblp May 15 22:17:46 [hal_lpadmin] File /usr/libexec/hal_lpadmin, line 717, in main_h = HalLpAdmin() May 15 22:17:46 [hal_lpadmin] File /usr/libexec/hal_lpadmin, line 686, in __init___self.addPrinter() May 15 22:17:46 [hal_lpadmin] File /usr/libexec/hal_lpadmin, line 700, in addPrinter_printer.add() May 15 22:17:46 [hal_lpadmin] File /usr/libexec/hal_lpadmin, line 541, in add_location=os.uname ()[1]) May 15 22:17:46 [hal_lpadmin] IPPError: (1280, 'server-error-internal- error') So, what happens if you build usblp as a module and you modprobe -rv ubslp? Does cups pick up your printer now? 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. 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. 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. 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. Wonko

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).

[gentoo-user] USB printer and new cups
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! Wonko

CUPS does not even have a hal use flag. Dale, help! Wonko 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. Dale :-) :-)

CUPS does not even have a hal use flag. Dale, help! Did you ever get this printer working with this particular gentoo installation? 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. If not have you seen this page: http://en.gentoo-wiki.com/wiki/Canon_Pixma_Series They make suggestions for drivers that may work.
