>>>Hi, Mark! I found the solution. It is so simple. Just create on every workstation, that is running this report the same 'custom' user-define size of paper that I've used with the setting. The EXPR field should not be touched at all. Thanks again.

> If I won't specify the custom size of the form , the report,that I've created does not align properly and some data are truncated,this one is still 8 1/2 X 11 paper size, but positioned all data differently (detail band,header,footer), because my setting for 'custom' user-defined size of printer are Width :1700 & Length:800.

My question is what did you use [software or utility?] on each user's workstation to create the user-defined paper size?
