Did this work previously in its current configuration? If so, you likely don't have a CUPS problem, but a USB problem - let's see your dmesg and lsusb output. Assuming this is a new setup: note the line: > Connection: lpd://salmo/var/spool/cups this doesn't make any sense. CUPS appears to be trying to print to itself. Hence, the password prompt. If it's connected via USB, (plugged in to a USB port on salmo, I hope), the line should show the location of the printing device. something like /dev/usblp0 or similar. CUPS does try to auto-detect USB printers - if you click Add Printer, is it listed? In my experience, USB is a less than ideal method to communicate with a printer. I much prefer Ethernet whenever possible. One other note: a quick search of my distro's package repository shows this: printconf - automatically configures USB and parallel printers with CUPS Perhaps yours has something similar available? -wes _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
