 One of the problems with Unix is its spotty support for printers. Before the advent of the Common Unix Printing System (CUPS), a particular printer needed a driver for, say, System V Unix, and a separate driver for FreeBSD. The problem has become particularly pronounced now that Linux is becoming more popular as a desktop operating system, where it competes with Windows and other operating systems under which printer installation is pretty easy. CUPS installs on all major Unix and Linux flavors, and handles the interface between printer and operating system. Driver writers can, therefore, write for CUPS and not worry about what's underneath. CUPS: Common Unix Printing System is first on the scene with CUPS documentation for installers, administrators, users, and programmers. It represents good work and is a worthwhile guide and reference that goes beyond freely available online documentation. Some readers may be disappointed that certain procedural parts of this book--notably that which has to do with compiling CUPS into the Unix kernel from source code--are exclusively Linux based. You can extrapolate other Unix flavors' procedures from the Unix instructions, but explicit how-to information would be nice. However, explanatory information on the Internet Printing Protocol (IPP, on which CUPS is based) is nicely written, and the CUPS documentation itself--particularly the instructions for developing printer drivers (in C) is excellent. Read this if you want to develop print Read more...
