Auto-detected USB printer stops working after reboot (Acer Aspire 1)
Canon portable printer is detected when USB cable is plugged in (using a Centronics parallel printer port to USB adapter cable). Acer computer prompts user to select correct driver. We select Canon BJC-70 from list. Printer test works fine using CUPS v1.3.x. We can print from any application without difficulty.
The printer configuration - localhost window lists the printer as "Unknown". I added the description "Canon" and the Device URI is listed as hal:///org/freedesktop/Hal/devices/usb_device_ffffffff_ffffffff_noserial_printer_noserial
Next time we boot the computer and try to print, application (or printer configuration "Printer Test" button) submits job. Printer job status hangs on Processing.
The best procedure we've come up so far is:
Acer Aspire 1 running Linpus Light.
Printer configuration (addition to URI entry above):
Pardon my newbieness - here are some thoughts:
Would our problem be because the restart causes the HAL to reserve a spot for the previously detected USB device but the printer is somehow recognized as a new device (with an appropriate driver) so the "install driver" doesn't show up?
I was expecting a URI of usb:/something something something rather than the hal:///yadda yadda.
I'm trying to think out of the box so any assistance would be appreciated.
Another Partial Solution
It seems like having the printer plugged in and on confuses the OS on a reboot.
Is this something that other people have noticed?
BTW: we have a networked HP printer and the Acer prints to it without a problem.
