PCL 5 emulation: HP
This section discusses the HP commands implemented in the Forms and Bar Code Card.

One-dimensional bar codes

With Forms and Bar Code Card installed, font selection commands in the incoming PCL 5 data
stream are analyzed for typeface characteristic values given in the table "PCL 5 function parameter
list" on page 22. If the typeface value is one of those given, then special bar code generation
firmware will process the font selection command. Otherwise, PCL 5 emulation proceeds as normal.

Defining characteristics

The following commands let you further define characteristics of the bar code:
Command Characteristic
Esc
Determines the location of human-readable text printed with the bar
(s#P
code.
Esc
Selects the font used for human-readable text.
(s#H
Esc
Selects the bar heights.
(s#V
Esc
Selects the bar widths.
(s#B
Esc
Selects the space widths.
(s#S
For more information on bar code characteristic parameters and default values, see "PCL 5 function
parameter list" on page 22.

Command structure considerations

These command structure considerations should be followed when implementing bar code
applications using the Forms and Bar Code Card:
• Always specify the typeface parameter, because it directs processing to the bar code
generation firmware.
• You must explicitly specify the characteristic values. If no value is specified, then the default
value is used. Previously specified non-default values are not retained.
