Chapter 5 Printer Commands
428M Operator’s Manual - 880028-0112 5-27
^A ^D COMMAND
X 79 Set print head dots/inch (dpi). This command sets the dot density of the
print head.
0 203DPI: This sets the printhead resolution to 203dpi. This requires that a
203dpi printhead is installed on the printer. If the setting is not set properly,
the printed image could produce
1 300DPI: This command tells the printer to use the Ethernet port the next time
it powers up. The Ethernet port is generally a third party device that provides
the printer with the connectivity of an Ethernet system. Internally, the signals
go into a serial port. The Ethernet is setup and configured separated from the
printer using the third party software and/or methods. By default, the printers
are configured with an IP address of 192.168.200.3 on Port 9100 at the
factory.
The only valid entries are ^A0 for 203dpi and ^A1 for 300dpi.
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.
