Would you be so kind to comment on something. According to HPLIP 
web-site in order to unlock the FULL functionality of
all-in-one device one has to use CUPS?


*Question: How are HPLIP and HPIJS related?*

Answer: HPIJS is a subcomponent of HPLIP. HPIJS provides basic printing 
support for non-postscript printers. HPIJS can operate in any spooler 
environment (including no spooler). HPIJS provides no I/O. HPLIP 
provides I/O for bi-directional communication, scanning, photo card 
access, and toolbox functionality. HPLIP requires the CUPS spooler.

end of quote.

Call me stupid but I do not understand the above. I have used probably 
as you and many other people HPIJS with LPD.
HPIJS are included in HPLIP so I would guess that I could use even the 
same printcap file with HPLIP and it should work.

If I want to unlock scanning I need the hpaio backhands for SANE and 
they are included in HPLIP. Now why the hack
do we need the CUPS. Is it possible that idiotic HP-toolbox talks only 
IPP so that one can not actually get the status of the
toner, paper, and other "advanced" functions unless use CUPS?

I really apologize for bothering you but I really want to understand how 
HPLIP works.
