A/UX: Printing Garbage When Starting A/UX (9/94)


I am running A/UX 3.0 on a Macintosh IIfx with 32MB of RAM. We have serially connected a line printer, using the "lp" system. The printer works, but when we start A/UX, the computer sends a lot of garbage to the printer. This continues until we turn off the printer. What causes this, and how can we avoid it?

Perhaps you had AppleTalk/LocalTalk printing configured before, and used either the modem (tty0) or print (tty1) port. Also, some unfinished print jobs left in the spooler might print out this way. Go to the /usr/spool/lp directory and check for anything left in the print queue.

Here are some other things you might want to check:

- Is the printer port (tty0 or tty1) getty disabled in the /etc/inittab
file?

- Use the "ps -ef" command to display all processes that might introduce
the problem.

- Is the 'lp' or 'lpd' daemon functioning properly?
