Checking system software settings in MS-DOS
If you are using a parallel cable and cannot print a text file using the MS-DOS
PRINT command, you may have a problem with your AUTOEXEC.BAT file.
Open the file and look for the following line:
MODE LPT1:=COM1 or MODE LPT1:=COM2
These lines indicate printing you are using a serial cable connection, and so you
should delete them, save the AUTOEXEC.BAT file, and try printing again.
Of course, if you are having problems printing with the optional Serial-To-
Parallel Interface Converter, you should conversely check to make sure that one
of the above lines is included in your AUTOEXEC.BAT file. The file must also
contain information on parameter settings. For details, see the user’s manual
that comes with the optional Serial-To-Parallel Interface Converter.
If the above is not the problem or if you make the above changes and still
experience problems printing using the MS-DOS PRINT command, refer to
your MS-DOS Users’ Guide or consult with your software dealer.
If you are successful in printing using MS-DOS PRINT command but cannot
print from an application, check to see what printer driver is select in the
application. See “Setting up for printing with MS-DOS” on page 43. If this does
not help, consult with your software dealer.
Checking the port settings in the User Setup Utility
❏ Start up the User Setup Utility (page 17).
❏ Select Port from the menu bar.
❏ Make sure that your printer cable is connected to the port selected in the list
of available ports.
If you are using a parallel cable, you will probably be using LPT1. If you are
using the optional Serial-To-Parallel Interface Converter, you should
normally be using COM1 or COM2.
❏ Exit the User Setup Utility and send the settings to the printer.
