Need Printer to use resident fonts

I have a PC that is using Client access that is on an AS/400 system. The printer is a Xerox 4512 laser jet frunning in PCL mode. I need ths printer to use the resident font that is on the printer. I can’t figure out how to modify client access or the printer function table to use the escape codes provided by Xerox. These codes don’t look like the ones already in the function table.

Can anyone help me to configure this printer to work properly. It works fine with WIN98 but our problem is with Client Access.
