Designing Labels Using LDS Chapter 4

means that a total of five format fields are to be generated. If the HFM were changed to 4,
only the first four format fields would be generated. The HFM value should never be larger
that the fields that are actually sent. This would cause the printer to produce corrupt
images.
4.4.2 LSX (Print Head Size X)
HFM,
LSX
, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to specify the width of the print head using dots as the unit of
measure. The maximum width of the LSX parameter is determined by the width of the print
head. LDS has been specifically designed to accommodate a variety of print head widths.
The printer LSX value should always be set to 1280.
4.4.3 LSY (Label Size Y)
HFM, LSX,
LSY
, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is used to specify the height of the label using dots as the unit of measure.
The maximum height is virtually unlimited and is dependant only with available printer
memory. The label sample (Figure 4-2) LSY measures 3” or 900 dots.
4.4.4 WEB (Web Size)
HFM, LSX, LSY,
WEB
, GAP, DPS, LCB, AGD, SPG, OFX, OFY
The WEB parameter is the width, measured in dots, of the webbing or backing material that
is found on the left side of a die-cut label. This parameter is used to introduce an offset to
accommodate the backing of die-cut media. The label sample (Figure 4-2) WEB measures
.0625” or 19 dots.
4.4.5 GAP (GAP Size)
HFM, LSX, LSY, WEB,
GAP
, DPS, LCB, AGD, SPG, OFX, OFY
This parameter is the height, measured in dots, of the registration mark used to identify the
beginning of a label. The label sample (Figure 4-2) GAP (distance of the backing material
between the labels) measures 0.125” or 38 dots.
4.4.6 DPS (Print Speed)
HFM, LSX, LSY, WEB, GAP,
DPS
, LCB, AGD, SPG, OFX, OFY
The DPS parameter is used to set the printing speed for the printer. Refer to Table 4-1 for
the list of print speeds, DPS values, and corresponding inches per second values. The
printer has a default speed of 3.5 inches per second (IPS), which is a DPS value of 7. To
print at greater speeds, change the DPS value to a lower setting as shown on Table 4-1.
Generally, better print quality is achieved by printing at lower speeds, however this is also
dependent on the media and contrast settings as well.
Labels per minute can be calculated by the equation below:
IPS x 60 seconds
Labels per Minute =
