On the “Margins” page of the dialog you may select whether or not to use margins and the size of the margins. If the “Don’t use” option is selected, no printable area border will be shown in the designer’s Page window, and all page contents will be printed correctly on any printer. But object’s sizes will not be the same on different printers.

If you leave this option unchecked, and all margin settings are zero, the pageborder will reflect the maximum printable area for the selected printer. You may find some chopping when you switch between reports designed for one printer to another, particularly between ink-jet and dot matrix. Ink-jet printers usually have a smaller printable area than a dot matrix due to the way they feed the paper.

If margins are set to non-zero values, a border will be shown in the report designer’s page window (using a hash line style). If you use dot matrix printers, pay close attention to the printable area: some dot matrix printers will not print if the object to be printed overruns the printable area, others will produce pages with the over-run printed on them. This obviously produces weird looking reports. In this case, you should set margins manually.
