PC Printing

Please excuse my ignorance in this subject.
We have a PC Basic program that takes some input numbers, does many 
calculations and then prints out a table of numbers.
We rewrote the program in RPGLE and now have the ability to create the tables 
on the iSeries.

Our problem is in controlling the printout.  We have a spool file on the 
iSeries that we redirect to the local PC printer which is an Epson LX300 impact 
printer.  When it runs from the PC Basic program the user is able to select 
draft mode on the printer and everything works fine.  When we print with a 
Client Access printer session to the same printer the printer automatically 
switches out of draft mode and the characters are smaller.  The width of the 
table is the same but the individual characters are too small to easily read.
We are printing from the same PC the difference being where the print file is 
coming from (PC Basic program or iSeries spool file).

Can anyone give me some clues as to how to control the printing on the PC 
connected printer?

Thanks,
