Print Head Size Commands

The 224 and 424 printers can use a variety of different print head sizes and densities.
^D78 and ^D79 commands (non-volatile) allow the printer to be setup thru software to drive
different print head sizes and densities. Power cycle or ^D32 is required before command
settings take affect.
Note: When using these commands, the ^D79 command MUST be sent prior to the ^D78
.

^A ^D COMMAND
X 79 Set print head dots/inch (dpi). This command sets the dot density of the
print head. This command MUST be sent BEFORE the # of Dots (^D78) is set
with the ^D78 command. The only valid entries are ^A0 for 203dpi and ^A1 for
300dpi as shown in the "Dots/Inch" column in the table above.
XX 78 Set print head number of dots. This command sets # of dots in the print
head. This command MUST be sent AFTER the dot density (dpi) is set with
the ^D79 command. The only valid entries for XX are the numbers in the "# of
Dots" column in the table above.
These are examples of how to use the ^D78 and ^D79 commands:
EXAMPLE #1: How to set the printer for a 640 dot, 300 dpi print head:
^A1^D79<CR>
^A640^D78<CR>
EXAMPLE #2: How to set the printer for an 832 dot, 203 dpi print head:
