Changing The Printer Settings - Epson LQ-300 User Manual

Interface
When this feature is set to Auto, the printer determines which
interface is receiving data and switches to that interface until
the end of the print job (when no data is received from the
selected interface for the amount of time specified). You can
specify either 10 seconds or 30 seconds.
Set this option to Parallel only if you want the printer to ignore
data from the serial interface or to Serial only if you want the
printer to ignore data from the parallel interface.
Bit rate, parity bit, data length, and ETX/ACK
These options are available only when the interface is set to
Serial. See your computer manual for the appropriate settings.
State reply
For normal operation, leave this option set to Off (default).

Changing the printer settings

printer's settings, you can use the Printer Setting mode. Here's
how:
Caution:
c
To print the help text, use paper at least 210 mm (8.3 inches)
wide for single sheets or 240 mm (9.5 inches) for continuous
paper; otherwise the print head prints directly on the platen.
Also make sure you have enough sheets of paper because the
printer prints several pages of help text.
1. Turn off the printer. Make sure the paper is loaded correctly.
