linux cups slow printing help



 I have a customer that I am transitioning from SCO Unix to RHEL.  The server is used for an application that generates simple text reports.  They have a variety of HP printers.  I need to be able to print this simple text output and set: landscape, lines-per-inch, character-per-inch, margins, printer tray.  Very doable with command line options to 'lp'.  The problem is that cusp takes by 124KB text file and turns into a 1.4MB binary (ghostscript?) file in the print queue.  Under SCO, and cups with the 'text-only' driver, printing takes 1:45 (~10 secs per page).  Under cups with any other driver (hpijs, pcl5e) printing takes 6:45 (~40 secs per page).  I can't use the text-only drivers because I need landscape, printer tray selection, etc. 

This horrid print speed isn't acceptable to the customer.  Any ideas on how to work around this? 

I only have two so far: 

1) Tell the customer to replace all printers with newer faster ones. 
2) Write my own PCL to wrap around the text files and print raw. 

There has got to be a better solution.  Any help, ideas, pointers will be greatly appreciated!
