P8-20 Mobile Printer CPCLProgramming Manual
PRESENT-AT Command
The PRESENT-AT command can be used to position the
media at the tear bar of the printer or at a location where
the printed label can be easily removed by the operator.
When a PRESENT-AT command is issued, the printer will
print a label and then, after a delay period, advance the
media a specified distance. It will then retract the media
the same distance before starting a new print job.
The “delay” parameter is used to avoid unnecessary
advance/retract operations when printing a batch of print
jobs. The PRESENT-AT command can be issued in a
label file or in a utilities command session
(!UTILITIES…PRINT)
Caution: When using this command an added buffer area of 18 dots should be
applied to the leading and trailing edges of the label. Registration between
any preprinting graphics on the media and the file being printed may vary
from label to label .
Format:
{command} {length} {delay}
where:
{command}:
PRESENT-AT
{length}:
Unit length in dot-lines the media is
advanced after printing and retracted
before printing the next label.
{delay}: The interval after printing the label the
printer waits prior to advancing the
media. Increments are in 1/8 of a
second. A delay of “1” is equivalent to
1/8
th
of a second. A delay of “4” is
equivalent to 1/2 second, etc.
