Bar Codes
To print bar codes, escape sequences are sent to the printer specifying the
type of code, bar code height, bar code header information, placement
information, and bar code data. The following five escape sequences are
used for bar code printing:
ESC*z#V Bar Code Selection
This sequence selects the type of bar code to be used in subsequent printing
of bar code data. If a number other than those available is selected, the
previously selected bar code type will be used. The following table lists the
bar code types available and their corresponding value field numbers.

Note
The Postnet Barcodes type 13 & 14 print 24 bars per inch. See the section
on 256x Postal Barcodes for information on the 20 bars per inch and 22.5
bars per inch Postal Barcodes.
ESC*z#H Bar Code Height
This escape sequence defines the height of the bar code label in tenths of an
inch as specified in the value field (#). To specify a bar code height of .8
inches, the ESC*z8H escape sequence would be sent to the printer. A zero in
the value field specifies that bar code height is determined by the current line
spacing (1/6 or 1/8 inch for 6/8 LPI respectively, or 1/3 or 1/4 inch for double-
high/double-wide). The default bar code height is 0.6 inches.
