To interrupt an MS-DOS command while it is executing, try one of the following commands:

Hold down the Ctrl key and press C

Hold down the Ctrl key and press Break.

Printer Problems

Below are some general steps to follow if you are having difficulty with your printer. If the problem persists and you need more detailed information, check your printer manual. You may see one of the following error messages:

901 Parallel port error

1101 Serial port error.

These error messages appear if you are having trouble with the port to which your printer is connected. If it is connected to the parallel port, you may see error number 901; if your printer uses the serial port, you may see error number 1101.

1.If your printer does not work correctly immediately after you install it, check that the printer has power and is properly connected to the computer. (Also, make sure your printer has paper in it.) See Chapter 1 or your printer manual for instructions.
