Overview
With the Forms and Bar Code Card installed, you can specify bar codes for printing in PCL 5 using
the following techniques:
1
Standard PCL 5 font selection commands (used in the HP BarDIMM Pro products)
2
Special Lexmark advanced PCL 5 commands for bar codes

Cursor positioning

Cursor positioning is set as follows when printing with the Forms and Bar Code Card:
• From the current cursor position, bar code printing begins at the bottom left corner of the left
bar.
• The cursor is located at the bottom right corner of the right bar when printing is complete.
• This cursor positioning applies with or without human-readable text.

Human-readable text

One-dimensional symbologies

Human-readable text can be specified with the bar codes.
Six different fonts are available for most human-readable text. See the Esc(s#H command in the
table "PCL 5 emulation escape sequences" on page 20.
The specified text can be automatically centered on the bar code, and scaled based on the width and
height of the bar code and the method of embedding.

Two-dimensional symbologies

Two-dimensional bar codes can encode thousands of characters, rendering human-readable
interpretation of the data impractical. Alternately, descriptive text, rather than literal text, may be
printed along with the symbol. If printed, any character size and font available may be selected, and
the text may be printed anywhere near the symbol. The text must not interfere with the bar code
symbol or its quiet zones.
