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 15. 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:
For more information on bar code characteristic parameters and default values, see “PCL 5 function
parameter list” on page 15.
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.
Command Characteristic
