RESETING A DEDICATED DOS PRINTER
From any where...
Type the letters: "LSETUP"
Type a "P"
For PORTS
Type a "P"
For PRINTER
The printer port shows either "DISABLED" or "DISQUALIFIED" or "ENABLED"
If the printer stoped unexpectedly then it will say "DISABLED"
This was because of low ink, out of paper, or not ready.
Type an "E"
Now the printer port shows "ENABLED"
After you have reset the printer, you can hit escape several times
or you can just leave the screen alone and each screen will time-out.
