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). > 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. 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 So, what happens if you build usblp as a module and you modprobe -rv ubslp?

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.
