I just upgraded from hamm to slink. I have found one problem with the upgrade in the lprng package. I downgraded to the hamm version until such time as it gets fixed. Basically after installing the new version, I could not print due to some time of permissions error. I have the standard lpd.conf and lpd.perms files as defined by Debian.
