Printer Commands Chapter 5
5-32 438TM Operator’s Manual - 880049-0113
^A ^D COMMAND
XX 36 Adjust Contrast Base: This non-volatile command is used to skew the entire
contrast window (^D35). Contrast settings above 150 reduce the overall life of
the printer. This command has a ^A range of 10 to 200%.
X 161 Contrast Limit: This command is used to set the contrast limit of the printer.
The command uses the same contrast values of the D36 command. When
this command is set, the printer will ignore all contrast settings that are above
the limit command.
5.4.4 Printer Restart / Reboot Commands
32 Restart Printer (Soft Restart): This command restarts the printer’s internal
software. The soft restart command is also used to start using certain non-
volatile system parameters (head parameter and soft switch commands).
1 143 Save and Reboot (Hard Reset): This command instructs the printer to save
statistics stored in RAM to non-volatile Flash memory and then actually resets
the printer hardware. Issuing this command is the equivalent of turning the
printer off and back on. Even though the software attempts to maximize the
number of writes, Flash memory does have a maximum number of writes so
the D143 command should only be sent when it is imperative that the
configuration is written to flash memory. The D32 command is typically
recommended to set the non-volatile commands that require a restart. The
printer will update and write the configuration to flash on normal power downs.
This command may be used to start using certain non-volatile system
parameters (head parameter and soft switch commands).
2 143 Save Backup 1 and Reboot (Hard Reset): This command operates just like
option 1 above and also saves a second set of configuration parameters into
the first backup position. If the printer powers on and does not detect a
configuration, it will first search the first backup position and restore the
configuration stored in this location. The command may be sent along with the
^A1^D143 command and is typically only sent when the configuration actually
changes.
3 143 Save Backup 2 and Reboot (Hard Reset): This command operates just like
option 1 above and also saves a third set of configuration parameters into
the second backup position. If the printer powers on and does not detect a
configuration, it will first search the first backup position. If it does not find a
configuration in the first backup, it will then search the second backup location
and restore the configuration stored in this location. The command may be
sent along with the ^A1^D143 and ^A2^D143 commands and is typically only
sent when the configuration actually changes.
5.4.5 Registration Commands
While the printer is designed to work with a wide variety of label media, it is sometimes
necessary to adjust the printer’s thresholds in order to obtain proper registration and
operation. The numerical value in which the printer senses a registration mark is referred as
the threshold value.
