This is now a real thing!!! 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
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 

Maybe most people who use computers want them just to work but I 
personally love to know how they do it. In detail:-)

Most Kind Regards,

Predrag Punosevac
