Data dump mode

This printer has a special feature to make it easy for experienced
users to find the cause of communication problems between the
printer and application programs. In data dump mode, an exact
printout of the codes reaching the printer is produced. Use paper at
least 11 inches wide on the LQ-950 and 14 inches wide on the
LQ- 1050.

LINE FEED buttons at the same time, while you turn on the
printer.
