Printing a Hex Dump
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.
Note:
❏ Before using hex dump mode, disable the bi-directional support setting in the printer driver.
