Compressing Raster Data

[!includePrint Support Apps]

Unidrv supports raster data compression using the following three formats:

  • Tagged Image File Format (TIFF), version 4.0

  • Delta-Row Compression (DRC)

  • East Asian Run-Length Encoding (FE-RLE)

These methods are defined in the HP PCL 5 Printer Language Technical Reference. (This resource may not be available in some languages and countries.)

You can include entries in a GPD file to indicate which of these compression formats your printer supports. You can also provide your own compression algorithm.
