Lexmark-Unique PCL5 Command Description
Support of new bar code functionality is not available in HP BarDIMM, which requires the new
Lexmark-unique PCL5 definitions that provide access to the new functionality. Two new commands
are implemented, ESC&x#W and ESC&y#W.
Bar Code Descriptor - ESC&x#W [descriptor data]
This new escape sequence is used to describe not only what bar code to print, but also all of the
parameter settings required to build the bar code. The first two bytes of this command always
designate the symbology. The remaining bytes are then interpreted accordingly, based on the
symbology. Each symbology has its own defined descriptor header.
The first two bytes are required. The remaining bytes are optional. If those bytes are not sent, the
settings are set to appropriate defaults. # is the number of bytes of descriptor data.
Transfer Bar Code Data - ESC&y#W [bar code data]
This new PCL5 command is used to transfer a raw block of bar code data to be encoded. The bar
code data is encoded according to what was specified in the last valid Bar Code Descriptor
command received. If no valid Descriptor is sent, then this command is ignored and the data is
flushed. # is the number of bytes of bar code data.
Compatibility Safeguard
These two new commands, if sent to an HP printer, are flushed and nothing prints. There is a
possibility that a future HP PCL5 enhancement could utilize the two escape sequences that have
