After booting have to re-plug, restart cups printer (SOLVED)

This is only a minor nuisance, but after I boot my computer I have to physically unplug the printer USB cable, plug it back in, and then visit localhost:631 to start the printer in CUPS. Is there any way for it to set the device permissions correctly on boot and start the printer automatically?

Thanks!

Do you have the coldplug package installed?

Oops, in re-emerging cups, I see that it tells you to install coldplug.

Good, that fixed having to replug the cable. I still had to start the printer in cups though.

I think the problem could be in my device URI. I have it set to "Device URI: device=/dev/usb/lp0" I did this by selecting (in the cups configuration utility) Device: LPD/LPR Host or Printer, then entering /dev/usb/lp0 as the device URI. Is that correct?

Okay, yeah, changing the device URI to USB Printer #1 fixed it.

Thanks for your help!

Is there another way beside coldplug to have a USB printer that is always plugged in working without replugging? My system runs very good without coldplug (e.g. fast boot time) and I would like to stay away from it. It's just a little overkill for the little printer problem, I think.

@r.abbott: Would you be so kind to delete the "solved" in your post title so that I have the chance to get an answer for my question? I hope it's OK for you that I "stole" you thread but I think my question is related. Thanks in advance.

AFAIK coldplug just loads modules for you at boot time. If you don't want to use coldplug you can just add the modules you want loaded at boot to /etc/modules.autoload.d/kernel-2.6 (assuming you are running a 2.6 kernel). In the case of a USB printer the module is called usblp.
