I'm using Version: 6.1.4.2 (x64). Calc spreadsheet.

All of a sudden when I go to print a page, the print preview is blank and nothing page prints out blank. It only happens on one document. Is there a secret button to “supress” printing or something? HELP. If I copy and paste into another document it’s fine. WHAT THE HECK DID i DO.

i hit submit and this page came back. I’m only asking one question.

Check to see if the print range had been altered. in the drop down menu Format/Print Ranges/Edit.
See if it is sett to a a set of rows or columns that are blank in your sheet

Following @AdmFubar, try to understand how to set pressure ranges.
