OK, here's something similar to what I want to do:

After user object is defined, map a printer name where

prtDevice = "L" & UserObj.physicalDeliveryOfficeName & "PRT"

resulting in a mapping something like

\\printserver\L00001PRT (where 00001 is the physicalDeliveryOfficeName for that user)

Somewhat make sense? I was confused in the initial post...the actual attribute I want to use is above, not companyLocation.
