I posted a question to Debian User about package conflicts between
hpoj(sp?) and hplip(sp?) that are for parallel HP printers and usb HP
printers. My HP 697C is parallel, and my HP psc1210 is usb.

Perhaps this question should also be posed to Debian KDE since one of
their hints in version 3.3 recommends CUPS which I have. I also have
Xprint stuff installed which was recommended for removal in a message
posted on Debian User. When I went into aptitude to do that, it seems
that aptitupde wanted to remove about half the packages. Since that
looked like wholesale destruction of the system, I was quite leery of
doing that! I'm somewhat confused about what to do next about the printer
conflicts. I am able to use localhost:631 to get into CUPS
administration. The hpoj package created an entry in ptal something about
mlc:usb: etc. I was wondering if this is the famous URI (Uniform Resource
Indicator?) that is supposed to find the usb printer which I think the
system picks up as usblp0. (That '0' is a zero.)

As you know, I'm running a sarge system upgraded from woody with a choice
of 2.4.18-bf2.4, 2.6.11. i686, and 2.6.12 i686 kernels. This is on a
Gateway 500 with a Pentium III (Katmai).

I wonder if it is possible to force aptitude to install those 2
conflicting packages and somehow match them to the appropriate printer?

No, hpoj and hplip should not conflict, at least not according to hpoj
website. This was fixed in hplip-0.9.3-3 (Debian unstable).
To fix this for your version:
mkdir hplip
cd hplip
apt-get source hplip
cd hplip-0.9.2
#the follow or manually editing debian/control
sed -i -e 's/hpoj, //' debian/control
dpkg-buildpackage -rfakeroot -b -uc -us
cd ..
dpkg -i hplip*.deb

See hpoj package description:
- An application programming interface (API) known as "PTAL" (Peripheral
Transport Abstraction Library) that hides the differences in accessing
devices connected via parallel, USB, or JetDirect.

Not cleanly without rebuilding the package (but that's easy, see above).

Thank you very much! I'm doing this from work and, once I get home from
work, hope to try it out within the week at the latest!

I also had to get a few extra packages. Fortunately, that was routine.
Aptitude installed about 15 more packages.

I found out that I had to force it.

And I apparently succeeded as follows:

gayle@Gcomm:~/drivers/hplip$ dpkg -l | grep hp
ii foomatic-db-hp 1.5-20050420-1 linuxprinting.org printer support -
database
ii hp-ppd 0.5 HP Postscript Printer Definition (PPD)
files
ii hp2xx 3.4.4-2 A HPGL converter into some vector- and
raste
ii hp48cc 1.3-3.1 C-like compiler which produces HP48 RPN
ii hpijs 2.1.2+0.9.2-2 HP Linux Printing and Imaging - gs IJS
drive
ii hplip 0.9.2-2 HP Linux Printing and Imaging System
(hplip)
ii hplip-data 0.9.2-2 HP Linux Printing and Imaging - data files
ii hpoj 0.91-4 HP OfficeJet Linux driver (hpoj)
ii hpscanpbm 0.3a-11 HP ScanJet scanning utility
gayle@Gcomm:~/drivers/hplip$

Well, that was the 'easy' part! Now I have to get it working together!
I still need to get CUPS appropriately configured. I can get into using
the browser and URL localhost:631 or the printer wizard. I don't know
which is best.

I appreciate the suggestions!

Actually, the "force-conflicts" was the wrong way :-(
It's easier and cleaner to edit the debian/control file and remove the faulty
conflict. If not, some tools (aptitude?) might automatically remove one of
them.

Easier? In the first case, you use dpkg (I always use --force-all, since by
this point you know there are no other errors - and I can never remember
which "force" option it is) and cut and paste the .deb name from the error
in apt-get/aptitude. In the latter, you have to edit a control file
(correctly). I'm sure it's cleaner, but I've never yet encountered a
situation where simply forcing a conflict didn't work.
