select papersource

[andmar]

i have written a printing module in visual basic.net which manages my reports and printjobs
i need help on the following:
the user must select a printer and papersource on a control panel
this settings i save to a database
so when a printjob has to print i read the settings from the database and select the printer and papersource and print the job
i can read the available printer and the available papersources
but i hang in the selection from the papersource
so how can i select the papersource?

another question is how do i change the papersource during one printjob
all reports with 1 page should be printed from tray1
all reports with more then 1 page the first page should be printed from tray1 and all other pages from tray2

i hope anyone can help me
thanks
