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.

1.To enter the data dump mode, hold down the FORM FEED and LINE FEED buttons at the same time, while you turn on the printer.

2.Next, run either an application program or one you have written in any programming language. Your printer prints all the codes sent to the printer in hexadecimal format as shown below:
