media types. The printer will print all fields that contain data and then advance the media by
the amount specified in the SPG parameter of the header when the default AGD of “1” is
entered in the header. This means that fields that are left blank or text data for the
associating format fields are left empty will not print.
For example: Imagine a receipt format that contains 100 lines. If data is provided for the
first 50 lines, the printer will not advance for the remaining 50 lines that have been left blank.
The printer would stop immediately after printing the 50th line and then advance the media
by the amount specified in the SPG header parameter.
When the AGD header parameter is set to “0”, the printer will advance the same amount of
media even when text data fields are left blank. In this case, the advance distance is
determined by adding the SPG parameter and LSY parameter values.
For example: Imagine the same format as mentioned above that has an LSY value of 900
(3” x 300 = 900), an SPG value of 385, and an AGD value of “0” that contains 100 format
lines. If text data is provided for the first 50 lines and the remaining 50 lines are left empty,
then the printer will print the first 50 lines, advance the next 50 lines, advance the remaining
LSY value, and then finally advance the SPG or 385 dots. Regardless of the format fields, if
the LSY is set to 900 and the SPG is set to 385 the printer will advance a total of 1285 dots
(900+385=1285).
4.4.7.3 Black Line Media (Reflective) (setting = 3)
The Reflective Black Line method is used when media uses a black line for a registration
mark; a “3” should be entered in the LCB parameter. This setting will detect the leading
edge of the black line by using the reflective sensor only. The light from the emitter in the
lower sensor is reflected down to the detector in the lower sensor.
Note: The transmissive sensor is still used to detect “paper out” conditions.
4.4.8 AGD (Activate Gap Detector)
HFM, LSX, LSY, WEB, GAP, DPS , LCB,
AGD
, SPG, OFX, OFY
This parameter selects the number of step (dot rows) that the printer will skip before
registration mark sensing is activated. This value is usually set to “1”. It is a good idea to
set it to a value to ignore areas of pre-printed or perforated stock that might cause incorrect
registration mark detection.
4.4.9 SPG (Steps Past Gap)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD,
SPG
, OFX, OFY
This parameter is used to specify the number of steps (thermal dots) to advance the media
after a registration mark has been detected. This parameter is required to properly register
print on each label. The table below lists proper SPG settings for particular printer
configurations when the LSY is greater than the D2G parameter value, the D2G value is
used.
