Reverse Video
The reverse video function inserts a black rectangle that is one dot larger than the contents
of the text string field that will be printed. The result would be that the text would be placed
as white on a black background area. This effect is the same as if the image was X
OR’ed
onto a black box or line. In fact, if the automatic black box is too small, the line draw feature
may be used to increase the size of the background black box. Refer to section 4.1 for
additional information regarding the reverse video function.
Ratios
The ratios are used in conjunction with the Codabar, Code 39, and I2 of 5 bar codes. This
value determines the size of the wide to narrow bar ratio. The narrow bar module is always
one dot by default. The actual size of the dot is based on the type of print head installed on
the printer. By using the SW and/or SH parameters, it is possible to multiply the narrow bar
module and then apply the various ratios to create the desired bar code size.
For example: An 8 dot per mm or 203 dots per inch pri
nt head has a dot every 0.0049”.
This would mean that the narrow bar module by default is 0.0049” and that a 2:1 ratio would
result in the wide bars equaling 0.0098”. Using the SW and/or SH parameters, depending
on the orientation of the bar code, it is possible to multiply and adjust the narrow bar
module. This would mean that for a 0 degree bar code, a SW value of 2 (2 x 0.0049) would
adjust the narrow bar module to 0.0098” and then applying a 2:1 ratio would produce wide
bars of 0.0196”(0.0098 x 2).
1.5.7 DN
(Direction)
XB, YB, CI, SW, SH, AI,
DN
, FO, FJ, FW, CS, FC, CC
This parameter is used to select the direction of the text. The only valid parameter for
direction is rightwards text. A selection of rightwards text would cause the characters to be
printed left to right.
1 Rightwards Direction (default)
1.5.8 FO (Field Orientation)
XB, YB, CI, SW, SH, AI, DN,
FO
, FJ, FW, CS, FC, CC
The values entered in this parameter are expressed in degrees. The normal orientation (0º)
is right side up as viewed from the front of the printer. The valid arguments are 0, 90, 180
and 270. The rotation is measured counter-clockwise.
0 0 degree (default)
90 90 degree
180 180 degree
270 270 degree
1.5.9 FJ (Field Justification)
XB, YB, CI, SW, SH, AI, DN, FO,
FJ
, FW, CS, FC, CC
The field justification or FJ controls the alignment, kerning, and the proportionality of text
and/or bar codes with respect to the type of composition used. Alignment is done side-to-
side (left, right, centered, or full justified to span the entire LSY distance) and vertically (on
or below baseline, which is an imaginary line extending from the starting coordinates along
the direction of the text), relative to the default (0 degree) orientation of text and/or bar
codes and the insertion point of the field. This means that whatever the direction and
