Controlling Print Quality - Datamax Prodigy Operator's Manual

6. "O####" COMMAND. CHANGING THE DEFAULT
LABEL OFFSET.
The "O####" command changes the label offset. The Printer will
accept the "####" string to be in the range of 0000 to 0999. The
Printer normally stops the label media at 0.20" past the printhead.
This means that the last label printed is still attached to the label
backing and can be removed by an operator.
If you are printing in batch mode and rewinding the labels, you may
want to have the label offset changed so that printing can begin on
the very bottom of a label.
This command is different from the "C####" command, which
changes the location of the print on the label. The "O####"
command actually changes the zero reference point of the label.

4.14 Controlling Print Quality

The Printer provides maximum flexibility by offering a direct thermal
and thermal transfer print capability. To provide this diverse printing
option, the Printer has a flexible set of printing controls.
The amount of heat applied per dot row and the rate at which the paper
moves under the head have the most effect on the images that are
printed. The Printer allows you to control these factors but also limits
them so you cannot ask the Printer to print an image that could be
damaging. For example, low cost direct thermal stocks have very high
reaction temperatures. It takes a lot of heat to make clear images on this
type of paper. The Printer allows two methods of compensation. The
burn time can be set to a greater value by using the "H" LABEL
FORMATTING command. This would cause more heat to be
transferred into the media, which would generate a darker image. The
second method would be to reduce the print speed with the "P" LABEL
FORMATTING command. This would allow the paper to remain under
the head for a longer amount of time. This would also allow more heat
to transfer into the media.
