I have very similar symptoms to ones described by Daniel. I'm on up-to- date 12.04, got Minolta PagePro 8L LPT printer also connected to USB via Prolific PL2305 USB<->LPT adapter. The combination was working just fine until I updated from previous LTS to this precise (12.04). Now if I try to print, job appears to queue, then disappears, printer light begins to flash (as if it was receiving/processing data) but nothing else happens. Light flashes seemingly forever and printer status is reported as "Idle - Sending data to printer."
First thing I noticed when I started debugging this was "Filter ... not found." lines in cups error log. They disappeared after I removed and re-added the printer, but it had no effect on the problem itself. Following sections "USB printer", "CUPS error_log", and "Capturing print job data" on https://wiki.ubuntu.com/DebuggingPrintingProblems I get.
