Printed output is not what you expect

If the printer does not print correctly, try the self test described on page 1-13. If the self test works properly, t e printer is all right and the problem probably lies in the coItputer, the software, or the interface cable. (Be sure to use a shielded cable.) If the self test does not work, contact your dealer or a qualified service person..

Check the printer settings within your software program.

Use the hex dump mode to pinpoint communication problems between the printer and your application program. To enter the hex dump mode, hold down the Load/Eject and Font buttons and turn on the printer. Then send data from the computer.
