Thank you so much for this how to! I was wondering myself why would one need CUPS to use HPLIP but I never had the gut to ask anybody as I didn't want to look like an idiot. In reality the only semi-serious document about setting HPLIP I have seen for FreeBSD is Daniel W. Steinbrook's how to which walks you through but doesn't explain how the things really work and why does he need CUPS. I learned a lot from your The FreeBSD Corporate Network's Guide. I would really love to see you personally updating chapter about printing in the Handbook. Chapter is well written but seems that it lacks details about filters and drivers necessary to set printers which speak only PCL. Most users including the University where I work do have some if not most printers which do NOT speak Post Script. The knowledge to edit the printcap file and how to utilize various filters seems to me as paramount importance. However, like probably on many other places the system administrators choose "easy" route which is using CUPS and buying printers that are documented to work with PPD files they can get from Linux Printing web-site. I do not think that they have every used foomatic rip to get PPD for a printer. Even worse they use Ubuntu for Printer Server and they are clueless what is really going on. At some point I was contemplating to buy http://www.amazon.com/CUPS-Common-Printing-System-White/dp/0672321963 and try to learn how really CUPS does work. The problem with that is that the more I learn about Unix Printing it is less clearly to me why the hack do we need CUPS anyway. For a really novice user I find apsfilter and running ./SETUP script far easier than using idiotic CUPS web-tool. Native LPD system is easy to trouble shoot, including network printing and I am not a system administrator by profession. Whole that mambo-jambo thing about security problems with LPD in the past seems absurd as even my home printer servers and stations are behind two layers of firewalls deep behind in the LAN zone. I would really love to see you writing a book about Unix printing as except the above book about CUPS I have not seen a single book entirely dedicated to Unix printing. I would love to learn from you advantages and disadvantages of common spooling systems LPD, LPRng, CUPS, and PDQ. I would love to see comprehensive paper explaining in the details printing process on the printers which speak PostScript or PCL. And trust me I did read blue and green book for Post Scrip language and are read through HP technical notes regarding CPL release. I would love to see comprehensive compassion of various auxiliary filters a2ps, apsfilter, magicfilter, ifhp, foomatic and explanation how they work. I would love to see driver comparation ghostscrip vs gutenprint vs hplip. I would love to see lots of examples of the printcap files which were used on real *BSD machines in various situations network situation including heavy network printing with various groups, priorities, and quotas. Maybe most people who use computers want them just to work but I personally love to know how they do it.
