To recover (personal) printer settings, you have to fetch the following files and directories from a proper Time Machine backup:
/etc/cups/ppd/ /etc/printers.conf /Library/Preferences/org.cups.printers.plist ~/Library/Preferences/com.apple.print.custompresets.forprinter.*.plist ~/Library/Printers/
and a
launchctl stop org.cups.cupsd launchctl start org.cups.cupsd
may help too
