Zebra Technologies 14245L-003 manual Set Form Length, 139, Syntax Qp1,p2,±p3

EPL Commands

Q

139

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.

Syntax Qp1,p2,[±p3]

Parameters This table identifies the parameters for this format:

Parameters		Details
p1	= Label length	Default Value: Set by the AutoSense of media
	measured in dots	Accepted Values: 0-65535
		• Distance between edges of the label or black line marks.
		• For continuous mode, the p1 parameter sets the feed
		distance between the end of one form and beginning of the
		next.
p2	= Gap length or	Accepted Values:
	thickness of black	16-240 (dots) for 203 dpi printers
	line	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 p2 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.
p3	= Offset length	Required for black line mode operation.
	measured in dots	Optional for Gap detect or continuous media modes. Use only
		positive offset values.

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.
