Printer or Scanner Problems
The printer or scanner does not work at all.
Check that the printer or scanner has power and is properly
connected to the computer. Also make sure your printer has
paper in it. If you are using more than one serial port, check the
primary and secondary port settings (COM1 and COM2) in
your application program and in the SETUP program. See
“Configuring integrated peripherals” in Chapter 2 for
information about serial port settings in SETUP.
If you connected a scanner to the parallel port, make sure the
port is set for bidirectional operation (ECP mode). See
“Configuring integrated peripherals” in Chapter 2 for more
information. If you use ECP mode, check your parallel device
software documentation for the correct DMA channel (DRQ)
setting; then set jumpers JP8 and JP9 to match the setting, if
necessary; see “Changing the Jumper Settings” in Chapter 4 for
more information.
The printer prints garbled information.
Check the printer manual for the printer’s correct DIP switch or
control panel settings. Also, make sure you have the proper
drivers installed for your printer and make sure you’ve
selected the correct printer within your software application.
