3.6 Dump Mode
After the self test, the printer enters the dump mode. In this mode, any characters
sent from the host computer will be printed in two columns, as shown. The
characters received will be shown in the first column, and their corresponding
hexadecimal values, in the second. This is often helpful to users for the
verification of programming commands or debugging of printer programs. Reset
the printer by turning the POWER switch off and on.
