[comp.sys.mac] How to check HP Laserjet IIP Serial Port: Doesn't work with MacPrint

ia4@cunixd.cc.columbia.edu (Imran Anwar) (11/18/90)

Have an HP LJ IIP hooked on parallel with my Atari Mega4 ST.  Works fine.
Now also have a Macintosh IIsi.  Got MacPrint, a Laserjet Driver for the
Macintosh, that works with LJ's serial port at 19,200.

Installed, made LJ settings, and tried to print.  Mac applications send page
to print, but the LJ front panel light does not light up, and nothing prints.

Returned MacPrint, got JetLink, another Mac driver for LJ printers. Same
problem.  No print.

The Mac's serial port is OK because a modem works with it with the same cable.
So the cable is OK too.

Is there any way I can check the Laserjet's serial port from the Atari ST or
from my roommate's IBM PC?  eg a DOS command(s), Basic Program, or something
like an Atari Desk Accessory would help confirm if I have a bad printer.

Appreciate your help/

Thanks
