I've noticed recently (12.0+??) that the Slackware 'adduser' script now
prompts to put new users in the 'cdrom' group (as well a 'video' and a couple
of others). This allows the user to eject the cdrom without needing to change
the udev permissions. (Not that learning how to set the permissions with udev
isn't a valuable thing to do!)
Something that's bugged me: I set up an automounter (runs are root) and it now
mounts my USB stick, USB external drive, etc. no problem. But then I find
that a FAT32 filesystem is mounted as 'root', so no access by me as an
unprivileged user! I added 'umask=000' to the automounter's mount options,
and that fixed it. Until now (maybe after an upgrade?) mount complains in the
log: unknown option umask=000. So I had to take it out again.

Buy an integrated network card for your printer! :)
Buy a Linksys wireless router running Linux, do the serial port hack on it,
and run your printer off serial. (Actually this probably a bad idea, as the
serial hack doesn't create a fully-featured serial port -- no flow control).
Buy a second-hand replacement wireless router with a parallel port.
Asus WL500B, WL500G (not the deluxe or premium models)
That one runs Linux and is compatible with 3rd-party firmware too (DD-WRT).
Umm.... out of ideas...
