Chapter 5 Printer Commands
438 Operator’s Manual - 880052-0100 5-29
^A ^D COMMAND
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 Slice Buffer Size and Set Starting Slice Number Commands
XX
92 Set Starting Slice Number: This non-volatile command adjusts the number of
slices (dot rows) generated before the printer starts moving the label stock.
The default is set to 67% of the slice buffer size. Anytime the size of the slice
buffer is changed (ref. ^D94 command), the Starting Slice # is also changed
automatically to a value that is 67% of the new slice buffer size. The
maximum number of slices (XX) is dependent on the size of the slice buffer
(^D94) command.
X 94 Set Slice Buffer Size: This non-volatile command is used to set the size of
the slice buffer that is used by the printer. If the slice buffer memory size is set
to low, the printer may start printing and then stop to process additional slices
before starting again. This typically happens on more dense formats were
more memory is required so that the printer can build the image to be printed
before actually printing the image. This command is used in conjunction with
the ^D92 command to fully optimize the slice buffer memory.

5.4.5 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).
