To copy the list of installed printers from one machine to another, copy the following files:
/etc/cups/printers.conf
/etc/cups/printers.conf.O
/etc/cups/ppd/*
~/Library/Printers/*
~/Library/Preferences/com.apple.print*
Make sure the files in /etc/cups retain the proper owner and group (root:_lp) and permissions (’u=rw,go=’ for the conf files and ‘u=rw,go=r’ for the ppd files).
You’ll also have to re-install any printer drivers that you installed on the old machine.
Restart after you’re done and System Preferences -> Print & Fax should now show your printer list.
