Hexadecimal dump
This procedure prints in hexadecimal format all codes (character codes and
control codes) that are sent to the printer by the computer. The printer does not
execute any control codes (such as 0A - linefeed), it just prints them out. The
hexadecimal dump is useful when you are writing programs for printer control.
❏Make sure that roll paper is loaded in the receipt printer.
❏Turn off the printer.
❏While holding down the control panel’s SLIP/RESUME button, turn the
printer back on to enter this mode. The printer beeps once to indicate in this
mode.
❏The printer will now print out the hexadecimal values of any data that is
subsequently sent to it from your computer. The last line buffer should be
flushed by pressing the RECEIPT button.
❏To exit this mode, turn the printer off.
Errors
There are three types of errors: automatic recovery errors that clear
automatically after some condition is attained, recoverable errors that require
some action by you before they clear, and non-recoverable errors that require
servicing by an authorized dealer. If a slip printer error occurs, the SLIP
indicator flashes quickly. If a receipt printer error occurs, the RECEIPT
indicator flashes quickly.
