Selecting Printer tray based on Doc type

[kislaylal]

I am trying to use CUPS4J to help in printing the docs with a specified Tray and media type but somehow what ever I do/give params, it prints from the default Tray of the printer.
Below is the code I am using to test out the functionality, can you please help me pointing out what am I missing here.
Rest of the params are working fine and I get the desired result except the Tray.
Commented code are the different options I tried but none worked. Please help in resolving.

I found a workaroud ... the printer that we are using is Lexmark brand and using the Lexmark's driver I am able to create 2 printer configuration in the CUPS server, 1 each for individual tray as default Tray (like PrinterX-T1 & PrinterX-T2) and then sending the printing command to each depending upon the need. This is clumsy I agree, but it works :)
My quest is to make it work cleaner with less management, please help!

Can you print docs files normally, why can I only print pdf, img

CUPS is the linux printing system that delivers many drivers to print different file types. I never heard of a print driver for CUPS that is able to print microsoft documents.
Cups4J just helps sending print jobs to CUPS from java. So if you can find a solution for your problem, please come back and report it here.
