Bumgarner) Newsgroups: comp.sys.next Subject: Re: blasting bitmaps (was Re: How did they make the printer so cheap?) Message-ID: Date: 20 Oct 88 12:20:15 GMT Organization: Carnegie Mellon Lines: 8 There is no need to compress the BitMap for port blast to the printer-- the printer has it's on channel on the DSP that is very, very fast. The bottle neck is the printer itself-- it prints at 8 PPM, not because of data transfer, but because that is all the faster the Cannon print engine will print. I would suspect that the computer has to wait for the printer when blasting-- unless the printer has a 2+ meg buffer on board. b.bum wb1j+@andrew.cmu.edu
