I am running 500,000 statement every month from 100 of cutomers that very important for me.

I would like to know who I can change the tray in the template FRX at run time to include a tray selection ESC sequence or function I need to use?

What I have done in other report was to add 4 text file label Tray1, Tray2, etc. with the ESC code for each tray and in the report template at the top I call the the Tray to include the ESC code that code need to be first. I use that with Konica 7585 ppm with PCL code and I have a other ESC code if I use the postscript driver.
