Q
Set Form Length
Description Use this command to set the form and gap length or black line thickness when
using the transmissive (gap) sensor, black line sensor, or for setting the printer into the
continuous media print mode.
The Q command will cause the printer to recalculate and reformat image buffer.

Parameters This table identifies the parameters for this format:
AutoSense routine does not detect black line or continuous media.
All EPL2 printers have a transmissive (gap) sensor designed to detect the top of each label or
tag. It does this in one of two ways:
• Sensing through the label liner at the gap between labels.
• Looking through a hole (notch) in the tag.
Printers equipped with a black line sensor can determine the top of each label or tag by sensing
a “black line” preprinted on the media backing.
Parameters Details
p
1
= Label length
measured in dots
Default Value: Set by the AutoSense of media
Accepted Values: 0-65535
• Distance between edges of the label or black line marks.
• For continuous mode, the p
1
parameter sets the feed
distance between the end of one form and beginning of the
next.
p
2
= Gap length or
thickness of black
line
Accepted Values:
16-240 (dots) for 203 dpi printers
18-240 (dots) for 300dpi printers
Gap Mode
By default, the printer is in Gap mode and parameters are set
with the media AutoSense.
Black Line Mode
Set p
2
to B plus black line thickness in dots. See the Gap
mode range.
Continuous Media Mode
Set p2 to 0 (zero)The transmissive (gap) sensor will beused to
detect the end of media.
p
3
= Offset length
measured in dots
Required for black line mode operation.
Optional for Gap detect or continuous media modes. Use only
positive offset values.
