Try the Gutenprint driver.

USB-parallel cables don't provide the bidirectional feedback (handshake) that many drivers need to function correctly - causing mid-page or single-page stall of the printer.

Try a different USB-parallel adapter, or, get a parallel print server and put the printer on the network. Used ones are about $25 on ebay.

Or, find and try 'usbtb,' a substitute USB print backend (comm w/ the printer) that fakes bidirectional feedback.

(caveat - I haven't used usbtb since mountain lion)
