printer tray-control in reports

Hi,

my problem is the tray choice on a printer HP LJ 3800 N in dependence from a user.

Therefore i used the following piece of code in the section:
IF USERID = ‘PE’ THEN
CurrReport.PAPERSOURCE(257)
ELSE
CurrReport.PAPERSOURCE(2);

The result is, that the first page was printed on the correct tray (3) and the following pages on the wrong one (2).

I also tried PAPERSOURCE(258) and (2) instead of (257).

Who has an idea?

Kind regards

Frank
