A DeskJet can print straight ASCII, so there gotta be another difference. 

Unless the printer expects LocalTalk on the serial port and can't handle 
either lower speed or data not encapsulated in LocalTalk packets. In the 
latter case, I'd expect it to print nothing at all. Linux doesn't do
LocalTalk, period.

Question to the original poster: did you change the serial speed to 38400
baud or less, and is this printer using LocalTalk protocol (i.e. shows up as
printer in the Chooser on a LocalTalk network)?
