pappl

A printer application framework

PAPPL is a C-based framework/library for developing CUPS Printer Applications, which are the recommended replacement for printer drivers. PAPPL supports LPrint and a Gutenprint Printer Application, but it is sufficiently general purpose to support any kind of printer or driver that can be used on desktops, servers and in embedded environments. PAPPL supports JPEG, PNG, PWG Raster, Apple Raster, and "raw" printing to printers connected via USB and network (AppSocket/JetDirect) connections. PAPPL provides access to the printer via its embedded IPP Everywhere service, either local to the computer or on your whole network, which can then be discovered and used by any application.
