Printer Command Language Format (PCL)

The Printer Command Language vector format was developed by Hewlett-Packard, specifically to provide a means of communication between computers and printers. The PCL files contain the commands and the HP printers parse and decode those commands. This format also includes HPGL. For more information about HPGL, refer to PLT.

This file format is not supported in the non-vector toolkits. Read support and write support for this format are provided in the LEADTOOLS Vector Imaging Pro toolkit and are unlocked when the Vector features are unlocked.

LEAD supports version 3.0 and 5.0 of this file format.

The default extensions used by this format are: PRN, PRT and PCL.

This format is used by Visual PCL, PCLTOOLS, redtitan EscapE and AutoVue.

This file format does not support layers or grouping, but it does support embedded raster objects.

PCL filter supports many features such as:

Support for Raster, text and rectangular area.

Support for Macros.

Enhanced performance of the filter.

Support for HPGL mode in PCL
