the printer's power off and then on again to resume normal printing.

firmware will occupy 1.5MB, so total available flash memory space for
downloads is 2.5MB bytes.
The DRAM on board is 8MB respectively. For DRAM, system and image
buffer will occupy it, so total available DRAM for downloads will be 256 K
bytes.
Dump Mode
After the self test, the printer enters the dump mode. In this mode, any charac-
ters 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 verifi-
cation of programming commands or debugging of printer programs. Reset the
printer by turning the POWER switch off and on.
