On a Centos-5.7 system, this printer works fine using a parallel cable but fails using the USB interface; the following appears on the CUPS page when I try to print a page: Unable to open device "hal:///org/freedesktop/Hal/devices/usb_device_6bc_268_AK11044671_if0_printer_no serial": Permission denied" Any suggestions? On a Fedora 14 system, the USB interface works, so it's not the printer. I've also tried another USB jack. Bob T.
