SYNOPSIS

foo2hp [options] < input > output

foo2hp converts PBM/PPM images to HP's proprietary ZjStream format for certain HP Color LaserJet printers. It enables printing on printers that lack native Linux drivers.
The tool handles raster-to-printer protocol conversion, managing page setup, color handling, and HP-specific encoding. It works as a CUPS filter backend.
foo2hp supports HP Color LaserJet 1600, 2600n, and similar models using ZjStream protocol.
