The Turbo Pascal source code can be found in Programming With Macintosh Turbo Pascal by Tom Swan (btw: that is a great book!).

Although I am not a Mac programmer nor have I tried this on a Mac, every horrendous task normally has a quick & dirty alternative. Turbo Pascal (and others, I might quess) allows one to open the serial port as a text file and then write to it. Something like this should work: var prntr : text; ch : char; begin rewrite( prntr, 'Printer:' ); write( prntr, ch ); end; I actually did this on the IttyBittyMachine (IBM-PC) to make a printer driver and font installer for my ImageWriter II.
