Epson PLQ-30 - Manual (Page 85)

❏ Prepare an A4 size sheet of paper before entering the hex dump printing mode.
❏ Always close the printer cover before printing. The printer does not print when the printer cover is
open.
To print a hex dump, follow the steps below.
1. Turn off the printer.
! Caution:
Whenever you turn off the printer, wait at least five seconds before turning it back on;
otherwise you may damage the printer.
2. Turn on the printer while holding the Offline button to enter hex dump.
3. Open a software program and send a print job to the printer. Your printer prints all the codes it
receives in hexadecimal format.
By comparing the characters printed in the right column with the printout of the hexadecimal
codes, you can check the codes the printer is receiving. If characters are printable, they appear in
the right column as ASCII characters. Nonprintable codes, such as control codes, are represented
by dots.
! Caution:
Do not turn off the printer while it is printing the hex dump. Always press the Offline button to
pause printing. Then turn off the printer.
