Printer debug test
If you are encountering issues with your printer, using the below debug command can help you discover what issues you are encountering.
Note: With most modern USB printers today this debug routine no longer works. This is a method of troubleshooting older computer printers.
1. Type debug at the MS-DOS prompt
2. At the - type in i379:
Anything less than eight for the second digit means printer error, first letter should be D, otherwise you will have some sort of error with the printer.
1 - 0001 9 - 1001 2 - 0010 A - 1010 3 - 0011 B - 1011 4 - 0100 C - 1100 5 - 0101 D - 1101 6 - 0110 E - 1110 7 - 0111 F - 1111
Example:
d = 1101 = (1)Selected (1)No paper error (0)Printer Acknowledged (1)Not busy
Note: To get out of the debug mode, hit "q" to quit.
