When I create a custom report and attempt to print, the title prints as a separate page. I can't find any settings to change this and helpdesk was somewhat less than helpful. Very, very frustrating and annoying.
Just checking a couple of basic things up front .... - is the print layout set for A4 and not USA Letter or other setting that drops 1/4" off the wrong end? - are there footer/header MARGINS forcing your custom content 'off the page' - have you tried printing to a PDF of size A4 (assuming you want A4, and portrait.... adjust accordingly..... just to separate your problem from being a printer setting issue, a custom report setting issue versus a reckon program issue.
It's always a handy diagnostic approach, to try your desired solution in a 'different' environment, such as another printer, or print to file or view on screen etc..... to see where the cause of the irritation is.
