Blank Pages in Crystal Report

Hi!
I have a obscure problem.
I have some reports (made in crystal report with landscape orientation) that are executed by browser (URL). In the screen the reports are showed ok, but when I send to the printer the report prints a blank page between the report pages.
The seagate web page says that I must to reduce the print scale. But what is "Print Scale" and how can I reduce it?

THANKS

hi Candiabreu
every printer has some default space to print the document. So In crystal report we have to set the page margins as Top=1.00 and bottom is 0.50 and left=0.50 and right is 0.50.
This is consider for almost every printer.

Another thing to check in the actual report is right click on the group section in the left side and choose change group. In the dialog that pops up make sure keep group together is not checked. If a group is particularly large, this can cause blanks to show up between groups due to how the crystal print engine tries to render the groups.
