Opera really does work with Cups - you will see your printer's

I've installed CUPS and actually _can_ see the printer
names in the dialog, but no printing takes place.
Test: I loaded google's homepage and pressed Ctrl+P Enter.
% lpq
HP_LaserJet_4000_Series is ready and printing
Rank Owner Job File(s) Total Size
active poly 20 Google - Opera 419840 bytes
And few seconds later:
% lpq
HP_LaserJet_4000_Series is ready
no entries
But nothing appear in the printer. It works from any
other application, even from command line.
Note that _those_ lp* tools are belonging to CUPS.
Which means - you really do use /usr/local/bin/lp and removed the system's
/usr/bin/lp* stuff?
Just to be sure

If you really want to use Cups [...]
Want? There's no such thing as wanting in relation to CUPS. :-)
[...] you have to set it up manually
Really? It was always advertised as doing everything totally
automatically.
- there isn't any automagic.
It recognized the printer (by scanning the network) correctly
and did even suggest the proper driver that allows me to
enable or disable the printer's special functions, such as
which tray to use, or if to duplex.
Can you print from the command-line
# lpr document.ps
?
Without problems. Even the pre-filters do work, e. g.
% lpr bla.c
or even
% lpr foo.jpg
CUPS does the preprocessing, the printer shows "JOB PROCESSING",
loads the paper and prints - just as expected, even like
without CUPS. :-)
(I've been using that "magic" with apsfilter before which
uses some pre-filters for various "non-printable" file
types, and then generates PCL using gs, which also allows
me to set printer-specific options.)
Oh, and I even wrote my own "PS only" printer filters,
also using gs, and putting them into /etc/printcap does
work.
% cat /opt/libexec/ps2pcl-dup.sh
#!/bin/sh
printf "\033&k2G" || exit 2
gs -q -dBATCH -dNOPAUSE -dPARANOIDSAFER -dSAFER -sPAPERSIZE=a4
-r600x600 -sDEVICE=ljet4d -dDuplex=true
-sOutputFile=- -&& exit 0
exit 2
Corresponding printcap entry:
Laserjet|ljet4d;r=600x600;q=high;c=full;p=a4;m=auto:\
:rm=192.168.100.100:\
:rp=raw:\
:lp=:\
:if=/opt/libexec/ps2pcl-dup.sh:\
:sd=/var/spool/lpd/Laserjet:\
:lf=/var/spool/lpd/Laserjet/log:\
:af=/var/spool/lpd/Laserjet/acct:\
:mx#0:\
:sh:
Of course in _this_ case print data has to be in PS format,
but that's no problem as it is the default output format
by all the programs that intend to print.
