Where is the Generic PCL Driver located within Mac OS X?

Hi Guys,

I have around 100 macs at my school on 10.7 (Lion) - i wish to add printer to them via a remote shell script or applescript through remote desktop. However i don't wish to have to install any drivers on these macbooks as this would defeat the purpose of working smarter and not harder.

here is my applescript:

do shell script "/usr/sbin/lpadmin -p benstestprinter -E -v lpd://10.32.164.24 -P /Library/Printers/PPDs/Contents/Resources/Fuji\\ Xerox\\ 4112\\ PS.gz -D \"WHOOO\""

I am happy that it is the correct syntax and adds printers correclty. However i have looked everywhere within the Above folder and over the internet for the location of Mac's Generic PCL Driver and cannot find it anywhere. Can anyone help me with this please?
