Hi
I write a lot of Informix ACE reports to HP lasers and i would suggest that you start with zero for the top, bottom and left. Start with a page length of 44 for landscape and 64 for portrait.
You may have to prefex some of your print statements with a ; to avoid Informix relentlesssly counting every "print" statement towards these totals - if you are also using hpgl formatting commands (that can be placed anyhere you like on a page).
Find the HP guidelines on the web and you will be able to create ACE reports with all the quality formatting and griding of a spreadsheet or word procesing table.
Cheers
Don
