Try inserting the following lines into a local printer script in /usr/spool/lp/admins/lp/interfaces, removing the equivalent lines from the original script.
Create an entry for office in /etc/hosts, and remove the line
'cp $file /u/PS2' if you don't want to keep a copy of the print file.
Save a copy of the original script.
