Another solution is to put the printer on the serial (phone) line, if it 
understands RS232. From this point, you can just send direct control 
characters as well as string to the print, as if ti were a modem or the 
like. If this small needle smasher doesn't understand RS232, you're out of 
luck. writing a device driver is hard, and writing a printer driver is 
harder. Get prepared for some hard assembly.
