Chapter 3
When LP+ Text Mode is set to “Auto Pass-thru,” non-PPI data is automatically
detected and passed through to the LP+ emulation (PPI data is processed
normally). If the hex commands 0x02 or 0x03 are received, they are treated
as binary data and passed through to the LP+ emulation; they are not treated
as the equivalent ^XA and ^XZ commands. System-generated line
terminators within commands are also passed through as binary data to the
LP+ emulation and not absorbed, as they are in the “Absorb” mode.
If LP+ Text Mode is set to “ZGL Quiet,” all data (including all PPI commands
except ~L0, ~L1, and ~L2) are passed through to the LP+ emulation. When
an ~Lx command is received, the corresponding front panel setting is updated
to reflect the current LP+ Text Mode value.
Text printing is useful in debugging label definitions, as it allows the incoming
data to be printed without entering hex dump mode. Simply placing ~L2
before the label definition (to enter Quiet mode) and ~L0 or ~L1 after it (to
return to PPI command processing) causes the label definition commands to
be printed rather than executed. Text generated via the base emulation is not
part of overlay data for any repetitive job.
^MC - Mp Clear
This command controls clearing of the label bitmap after printing. PPI may not
keep the previous label as a bitmap, but as text.
^MD - Media Darkness
Identical darkness values may not produce the same darkness on your printer
as ZPL.
^MN - Media tracking
This command selects the type of media the printer is using: continuous,
transmissive, or reflective.
^PF - Slew Dot Rows
With PPI, a slew speed increase may not occur since PSA slew definition and
use may be different than ZPL.
~PH / ^PH - Slew to Home
The PPI ONLINE light is illuminated when the printer is online.
^PO - Print Orientation
The following orientation parameter values are allowed:
N: No rotation (Normal)
R: Rotate 90 degrees (Landscape)
I : Rotate 180 degrees (Inverted)
B: Rotate 270 degrees (Inverted Landscape)
