Printbill is reported to work on the following platforms

Debian GNU/Linux 3.0+ (sid and woody - definitely works here because that's
where I use it).

FreeBSD 4.6-RELEASE (this is now an officially supported platform)

Slackware 7.x (others use this at UoW, so I know it works there)

RedHat 6.2, 7.0, 7.1 and 7.2 (I don't use RedHat much, but I have a
more-or-less working .spec file so you can create your own RPM)

Mandrake (reported to work)

Solaris 8 (reported to work)

I think it should also work on SuSE, I have no idea about Caldera or any of
the more obscure distributions. If it's Debian or RedHat derived it probably
will work.
