IBM-compatible computer running the PC-DOS™ or MS-DO S operating
system, go to step 9. If not, go to step 4.
4. Unplug the AC power cord from the printer.
5. Disconnect all data input cables from the printer interfaces.
6. Connect a parallel data cable to the LPT1 port or a serial data cable to th e
COM1 port of an IBM-compatible computer running the PC-DOS or
MS-DOS operating system.
7. Connect the data cable to the appropriate I/O port of the printer.
