insert the paper carefully into the printer. The printer will
automatically grip the paper and start the test print.
Note
If required, you can pause the test print by pressing
the SEL button and then resume the test print by again
pressing the SEL button.
5. When the test print has completed, the paper is
automatically ejected.

Connecting to a computer ____
In this section you will connect your printer to a computer,
install the printer driver in your computer and print a test
page.
Connecting the printer to a computer
Interfaces
Your printer is equipped with two data interfaces:
• Parallel: for direct connection to a PC. This port requires
a bi-directional (IEEE 1284 compliant) parallel cable.
• USB: for connection to a PC running Windows 98 or
above. This port requires a shielded cable less than 5m
long conforming to USB version 2.0.
Note
Interface cables are not supplied with your printer.
The following interfaces are available as optional accessories
and are described in their accompanying installation
documentation:
• RS232 Serial interface
• 100BASE-TX/10BASE-T network connection
Note
It is not recommended that you use either the parallel
or USB port when the RS-232C or OL7120e option is
installed in this product.
CAUTION!
Do not use both parallel and USB printing together.

Connecting to a computer > 13
