99% of our printing is plain old text reports

We have begun to convert our Unix systems to Linux and CUPS.  The problem is 
99% of our printing is plain old text reports.  Everything is getting converted 
up to postscript then back down and what we are seeing is, a lot of wasted cpu 
cycles and the number of bytes we are sending per print job has gone up 10 
fold.  This has to be a common problem.  Does anyone know where someone 
documented how to get around this?  

Thank you
