Postscript Emulation Operator - Lexmark T656 Technical Reference Manual

PostScript emulation operator

Operator Function/parameters
barcodeshow String dict barcodeshow
This function paints the specified bar code symbol at the currentpoint and advances the
currentpoint by the symbol's displacement (as returned by the barcodewidth operator).
This is similar to the show operator.
Example:
(01234567890)
<<
/Symbology /UPC-A
/EmbedText /HalfEmbedded
/FontName
>> barcodeshow
This operation will print a UPC-A symbol starting at the currentpoint with the data
half-embedded using the OCR-B font. The default quiet zone of ¼ inch at the start and
end of the bar code will be used. The value used for height will be the default, 620. The
values for bars and spaces will also be the defaults, [8 16 24 32]. The /Special key
defaults to false, so the checksum will be printed at the bottom left of the bar code. For
the UPC-A symbology, the checksum character always prints when embedded text is
specified, so /PrintCheckChar is irrelevant.
/OCR-B
