Printing to Non Default Printers and Various Trays

a) I am trying to use the "printer.printers.Indexof(string printer 
name & location)" function in the Delphi VCL to get non default 
printers to print Quick Report Docs.  The return value is always -1, 
ie default. I have a number of diffenent window printers installed - 
what are the tricks to getting the printer index numbers?

b) I also need to direct Reports to various trays on printers - how 
do you use the outputbin property in quick Reports to do this?

Any help greatly appreciated.

regards,

Chris
