Hello all!
I was happily computing away on my '030 NeXT and went
to print something. I got an error message saying that
I did not have a printer attached.
After making a quick check of all cables and retrying
to no avail, I tried using the command
/usr/etc/nppower on
The command returns: ?Could not open /dev/np0!
The man page on nppower says:
`?Could not open /dev/np0!' will be printed if no printer is
connect to the printer port.
Well, since then, I have ohm'd out the printer cable. It's ok. I checked
to make sure I had AC power to the printer. That's fine too.
I even pulled the metal plate off the bottom of the printer and looked
around. I removed the little board that the interface cable plugs in
to and saw a fuse on it. I checked the fuse -- it's good.
I also tried booting off another disk to make sure that I didn't have
a software problem.
Does anyone have any ideas of what else I might try?
Thanks a million for any advice!
