Modify Mandatory user roaming Profile

Hi, We run a 2003 server with XP workstations and one domain, we recently had the Mandatory user roaming profile set-up on the server,but we now want to modify it so as to alow all the children to be able to print from the default network printer. When the profile was set-up the IT person didn’t check to see if they could print to the printer, that person has now moved overseas.
