Yeah, Linux Mint 14 is based off of Ubuntu 12.10.
One thing that may happen - some things look at your distro name for configuration purposes. Pretty sure this isn't the case here, but if it's failing with a message like "your distro of Ubuntu isn't supported", then this might be what's causing it.
If this is the case, you can sometime figure out a way to lie to it.
Example (this is from the debathena installation script)
Now, I'm running Linux Mint 12, lisa, so this script gets confused because it doesn't know what lisa is. But I can replace distro=`lsb_release -cs` with distro=oneiric.
case $distro in
output "The release you are running ($distro) is not supported"
output "and installing Debathena on it is probably a bad idea."
if ! test -f /root/pxe-install-flag; then
ask "Are you sure you want to proceed? [y/N] " n
[ y != "$answer" ] && exit 1
error "The release you are running ($distro) is no longer supported."
error "Generally, Debathena de-supports releases when they are no longer"
error "supported by upstream. If you believe you received this message"
error "in error, please contact firstname.lastname@example.org."
error "Unsupported release codename: $distro"
error "Sorry, Debathena does not support installation on this release at this time."
error "(New releases may not be supported immediately after their release)."
error "If you believe you are running a supported release or have questions,"
error "please contact email@example.com"
But this can get pretty complicated, and it's probably not your issue. It is, however, one of few things that can cause an install to fail on Linux Mint 14 but not Ubuntu 12.10.
Another thing is that 12.10 is still pretty new; there's a (slim) possibility that your printer driver just doesn't work yet on 12.10. If this is the case, moving to Ubuntu 12.04 probably will solve your issue. Unfortunately the only way to get to Ubuntu 12.04 is to do a clean install - in other words, back everything up and install Ubuntu 12.04 over your current Linux Mint 14.
So, yeah, what printer do you have?
