If you are an experienced user or a programmer, you can print a hexadecimal dump to isolate communication problems between the printer and your software program. In hex dump mode, the printer prints all data received from the computer as hexadecimal values.
You can print a hex dump using either single sheets or continuous paper. See
Labels for instructions on loading continuous paper, or
Loading Single Sheets in the Top Paper Slot for instructions on loading single sheets.
If characters are printable, they appear in the right column as ASCII characters. Nonprintable codes, such as control codes, are represented by dots. By comparing the characters printed in the right column with the printout of the hexadecimal codes, you can check the codes the printer is receiving.
