Setting printer tray using bin Name

[Feng]

Hi

In the printout and createnewdocument methods of mailingLabel, the lasertray option only seems to accept a long value. Using some Visual Basic functions, I was able to obtain the bin Names of active printers. However, the bin Number values were not good enough, because it always just returned the "custom" papersource value

So, is it possible for me to select the bin to be used just by using the bin name and not the bin number

Thank
Feng
