Hi Pramod. There are two things you can do. First, Fox Power Printer will allow you to programmaticly select which paper tray is used on a printer You can get it at
www.foxprinter.com.
Secondly, you can use your report (xyz.frx) as a table (use xyz.frx IN 0) and delete the TAG and TAG2 fields in the first row and try editing the EXPR field with the tray information.
Good luck.
Rob.
