Using The Data Dump Mode - Epson LQ-1050 User Manual

Using the Data Dump Mode

The data dump mode is a special feature that makes it easy for
experienced users to identify the cause of communication problems
between the printer and application programs. The data dump
mode gives a printout of the codes reaching the printer.
To use the data dump mode, follow these steps:
1. Make sure that the printer is loaded with either single-sheet or
continuous paper.
2. If the printer is on, switch it off, then hold down the FORM FEED
and LINE FEED buttons at the same time you turn on the printer.
