Class Series 2 Programmer’s Manual 87
(PA) Present Adjust – This command fine-tunes the Present Distance setting in
dots to compensate for slight mechanical differences sometimes evident if multiple
printers share label formats. The EX2 accepts this command for backward
compatibility only, limited in range (28-228). KcQQQ response shows the
Present Adjust Fine Tune (PJ) equivalent value.
(PC) Print Contrast – This command adjusts the relative print edge (gray)
component of the print quality, which allows fine-tuning for specific media/ribbon
mix.
(PD) Present Distance – This command sets the label stop position past the start
of print. When the next label format is received, the printer will automatically
backfeed to the start position. If the present distance is set to zero, the printer will
operate without reversing. (See Stop Location, below).
(PE) Peel Mode – This command, when enabled, specifies that a Feed operation be
prevented when the label is presented and not removed, or if the printer is to wait
for the GPIO start of print signal.
(PJ) Present Adjust Fine Tune – This command fine-tunes the Present Distance
setting in dots to compensate for slight mechanical differences sometimes evident if
multiple printers share label formats.
(PL) Printer Level – This command is used to upgrade the software feature level of
the printer.
(PM) Pause Mode – See J for command details.
