Don Lancaster has been using Applewriter (both DOS 3.3 & ProDOS, I believe v2.1) for years to send raw postscript to laser printers. If memory serves, he claims it beats _anything_. Something like 56,000 baud out the serial port on a IIe. Although his recent "Ask the Guru" columns in Computer Shopper are more Mac oriented, you could check them out for appropriate addresses.

Yes, but I don't think the PostScript files were generated by AppleWriter -- Lancaster is one of the few PostScript sensei's in existence. To read some of his columns is to see PostScript explored as a language in itself and not just 'the thing that makes the printer work'. >If memory serves, he claims it beats _anything_. Something like >56,000 baud out the serial port on a IIe. That's 57,600 baud out the game port. Lancaster wrote his own printer driver that toggles one of the Announciator outputs so that it looks like the output of a serial chip at 57K baud -- run this through an MC1488 or MAX232 and you have a transmit-only serial port running at 57Kbps. Lancaster's claim is that the AppleTalk protocols used by the printer in a shared environment have so much overhead that the overall throughput is less than a direct 57Kbps serial connection.
