Data Dump Mode
Data dump mode is a special feature that allows experienced users
to find the cause of communication problems between the
printer
and application programs. In data dump mode, the printer
produces
an exact printout of the codes it receives.
To use data dump mode, follow these steps:
1.
Make sure that paper is loaded and the printer is off.
2. Hold down the
FORM FEED
and
LINE FEED
buttons and turn on
the printer.
3. Next, run either an application program or a program you have
written in any programming language. Your printer prints all
the codes it receives in hexadecimal format, as shown below.
