windows xp pro always uses guest account when receiving print jobs from network

Windows XP pro always uses guest account as owner when
receiving print jobs from network. How to change ?

Situation:
1 windows98 client machine, username workstation1
1 windowsXP home client machine, user account workstation2
1 windowsXP pro print server machine, user account server

server is connected to a network printer, server shares
this printer as \\server\printer

when workstation1 and workstation2 prints through
\\server\printer, the owner of the jobs are
always "Guest". where as if you print from server the
owner of the job is "server", same as the user account

How to get around this ? if workstation1 prints, owner is
displayed as workstation1 not Guest
