I think there's a few more issues going on then permissions in getting cups to work. I never did find a way to get a remaster working with cups, although everything else works. All files look fine, everything is there. No errors, cups doesn't recognize the print job. Tried with and without a pupsave, installing the printer from scratch (which seems to install okay). Print a test file, nothing, no jobs listed*. USB printer is correctly listed as "online", and works okay with original distro.
*EDIT: or "job completed" but no printout; or filter errors for geany.

I thought that I would play around with this issue some more. I took the lupu_520.sfs and manually unsquashed it. I then installed the HP printer driver package into the unsquashed file system, along with the files to represent an installed printer. I then resquashed it, leaving all the /var folders empty, like they are in the original sfs.
I then used the new sfs in a fresh Lupu frugal install with no pupsave. The HP printer was recognized and worked properly.

Yeah..no problem at all for my networked HP940c either; in fact I can print with my old pupsave. My USB connected HP laserjet Pll02w is a different matter: Here's the listing in cups:
P1102w Foomatic/foo2zjs-z2 (recommended) Idle - "Printer is now online."
Print a test page, and no jobs show even show up. I remastered by simply removing homebank from lupu_520.sfs and resquashing; didn't touch any /var or /etc files.
EDIT: using "lp -d HP_LaserJet_Professional_P1102w" I can get an error:
"/usr/lib/cups/filter/foomatic-rip failed"
Must be driver specific. Strange it works fine on the original distro..Have no idea why the remaster breaks it, though.

Is this one of the printers that requires the hot-plug firmware download? I wonder if it's not working.

Yes, foo2zjs includes it.

Lots of things can cause this message. I would put CUPS in debug mode and see if you can track it down.
1. Open /etc/cups/cupsd.conf
2. Change "loglevel info" to "loglevel debug"
3. Restart CUPS
4. Print a test page
5. Go to /var/log/cups
6. Open the error log file
7. Start at the bottom and work up

I'm getting different logs for different attempts; was getting a "Dirty files" error, but then got:
/usr/bin/foo2zjs-wrapper: line 182: /dev/null: Permission denied
/usr/bin/foo2zjs-pstops: line 111: 3848 Broken pipe
(/usr/lib/cups/filter/foomatic-rip) exited with no errors.
line 111 is just any argument, so nothing is getting passed. I don't think the /dev/null issue should stop anything, but may be wrong.

Have a look at the permissions on /dev/null. I''m seeing 666.

That was it....works. The remaster must have changed it to 644. Nice thinking! Sure glad we have a cups master on board.

Glad to help.
Like I said, there's nothing fundamentally wrong with CUPS. But you need to recognize how it behaves in an all-root environment.
