^A ^D Command
32 Reset Machine: Restores printer to power-up settings.
33 Display Model and Revision Number: Displays important reference numbers.
35 Contrast Window Adjust: Adjusts to a percentage of current contrast base. Used
for temporary variations in paper and should be lowered for ladder style (vertical)
barcodes. This command should be placed directly before the ^D57 command in a
format file. This adjustment has a range from 60% to 140% in 1 % increments. The
sequence ^A110^D355 will set the print contrast 10% darker than standard.
("Standard" is determined and visually calibrated by adjusting the permanent ^D36
command.)
XX 55 Select Default Label Layout: Select from the ROM power-up label layout. Only
used if you have a special lay-out burned into the ROM by Microcom. ^A selects
which one (1-8), if more than one are present.
56 End User Defined Field Definitions: Tells the printer that all field definitions are
complete.
57 Enter Label Format Mode: This tells the printer that information for a label is
following
93 Load Control Code Recognition Status: Some mainframe, mini-computer, and
special-purpose computers cannot send ASCII characters under 20 hex or send
these numbers for reasons other than 465 operation ( spooler initialization, etc). In
order to maintain proper flow control, the 465 printer will ignore everything under 20
hex if so directed. There is also an battery backed ram dip switch (see section 5.3)
that will enable the printer to enter this mode upon power-up. (Note: if control code
recognition is disabled, the printer will not process the 1B hex (ESC) character and
therefore will not be able to store data streams.)
0 Enable control code recognition.
1 Disable control code recognition.
