LaserWriter: Serial Printing from MicroChannel System



I have a MiniMicro 386 with a microchannel bus. I'm in a Macintosh
environment and want to print to the LaserWriter IINT.

I bought a Radio Shack cable 9- to 25-pin with transmit and receive
reversed. I put the LaserWriter IINT into Diablo 630 Emulation Mode. When
I tried to print, signals were sent to the printer but all that came out
was a blank sheet. I then used a straight-through RS-232 cable with a null
modem and got the same results.

Any suggestions?

The problem printing serially could be caused by a number of things, but a
straight-through cable with a null modem at the LaserWriter end should
provide a workable solution.

However, you also need to make a couple of Mode Command statements to
direct the output correctly to the LaserWriter. The commands are:

Mode: LPT1 96,N,8,1,P
Mode: LPT1 = COM1
