Depends on if ghostscript (or other drivers) support the 740. ?? (asks
someone who has a 740... :-)

As everyone has mentioned, you can do it. :-)

Transmitting is fine. Receiving A LITTLE DATA is ok too. The problem is
the chip only has a 3-byte fifo. If you don't send more than 3 bytes
before the driver can empty the fifo, you're ok. So like a once-every-
other-second status byte like DeskWriters (well older ones) send is ok.

That would be my concern, though I think a 650 would be a bit better.

Take care,
