A lot of people are mentioning the need to deal with the new lpr tools being at /usr/local/bin. I found that adding a symmlink from /usr/bin/lpr to /usr/local/bin/lpr, etc. to help with programs that expect to find lpr at that exact location.
Using a symlink will make life much easier with a few programs, since everything finds what it needs at either location. You will need to refresh the symlink after each upgrade. Backup the /usr/bin files just in case you really do need them later. Good luck! Printing is so damned easy or so brutally hard. ;-{)> -- Chris
