1.3 PCL Escape Sequences
To print from Unix or DOS systems you must send the appropriate PCL escape
sequences to print the bar code font you require. Example escape sequences are
shown below:
Code128TT-Regular : esc(12Yesc(s1p#v0s0b28685T
Code128-NarrowTT-Regular : esc(12Yesc(s1p#v0s0b28686T
Code128-WideTT-Regular : esc(12Yesc(s1p#v0s0b28687T
(#: point size 0.25 – 999.75)
Replace the hash (#) with the relevant point size. For example, to print a bar code
that is one inch (25.4 mm) high, substitute ‘#’ with ‘72’. To print a bar code half and
inch (12.7 mm) high, use 36.
To switch back to printing normal fonts in the typestyle you expect, print the PCL font
list from the printer control panel, and refer to the escape sequence shown on the
print out.
