AS-10, TCI=44
AS-10 is not widely used. It is variable length and encodes the numeric values 1234567890
only.
7.2 DESIGNING WITH BAR CODES
When 0 and 180 degree bar codes are X multiplied (CMX), the space between characters is
also multiplied to maintain the correct ratios. The printer will do this internally. Therefore, when
multiplying bar codes, use the default value for the spacing element (SP) in the field
parameters. On some bar codes (CODE 39 ...) you may choose a larger spacing than the
printer default, but you may not use a smaller spacing.
If the Y multiplier (CMY) is not multiplied, a bar code with a vertical length of one dot is
produced. Of course, this will not be picked up by scanners. Multiply the Y co-ordinate to the
proper height. For example: Multiply the Y co-ordinate (CMY) by 203 to create a one inch tall
bar code.
If the bar code is in a ladder (or vertical) orientation (90 and 270 degrees), multiply CMY for
width, and CMX for bar code length. It may be necessary to slightly adjust the contrast window
and/or adjust the print speed due to the "bleeding" effect caused by heat build up in the print
head.
