This looks like a kernel-level problem for me. All kernel modules for the parallel port are loaded (parport, parport_pc, and lp), but the printer's ID is not appearing in any of the /proc/sys/dev/parport/parport*/autoprobe* files.
As you had this printer already working on your machine, I assume that the BIOS settings for your parallel port are correct for bi-directional access. -- since updating to edgy, HP Deskjet 600 is not detected at all https://launchpad.net/bugs/59934 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
