I don't think these are the same bug, but I agree that Cups has become more flaky.
In my current Karmic installation, lsusb detects the PL-2305 correctly as: Bus 001 Device 007: ID 067b:2305 Prolific Technology, Inc. PL2305 Parallel Port My problem is that the printer connected to the PL-2305 always works for the first print job after a reboot of the computer, but always fails for all subsequent print jobs, with the CUPS administration page log saying: HP_LaserJet_6L-96 Test Page anonymous 1k Unknown completed at Fri 30 Oct 2009 04:05:53 PM EST "Unable to write 8192 bytes to printer!"
