Hi Carlo,
Sorry I was sure they had fixed this.... I confirmed it will not print a landscape report.
I'll have to look into it and get DEV to fix it it is our issue.
Update:
Hide the CR Viewers print button and create your and then use the same API the viewer should be using:
doc.PrintToPrinter(1, true, 1, 1);
That works... I'll escalate to DEV for SP 17 fix.
Thanks again
Don
