Auto-detected USB printer stops working after reboot (Acer Aspire 1)
Problem:
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. Troubleshooting attempts:
Partial Solution The best procedure we've come up so far is:
Additional Information 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
If:
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. |
