Has anyone out there written a device driver that would allow printed
output (LPT1:) to be directed to a serial printer AND would then pace
the output with the ETX/ACK protocol?

I have a Diablo 1620 printer hooked up to the serial port of my compaq,
and it works fine with Wordstar at 1200 baud because I can make Worstar
use the ETX/ACK protocol.  I'd like to be able to use DOS 2.0's print
spooler, but when I redirect parallel output to the printer, the printer
buffer overflows.

This printer won't use any protocol other than ETX/ACK.  When I bought
new ROM's that would add XON/XOFF protocol, and also a hardwired
protocol using DTR, Wordstar stopped printing correctly.
