If some of the document should have two or more columns, then select those sections and set the number of columns at 2 or whatever number of columns you want then select the rest of the document and set the number of columns at 1.

Then select everything (Control+A) and go to the Page Layout menu, and under Columns, choose 1 for the number of columns. (Thanks to my manager at work, Michael Bowers, for discovering this and the solution.) First, make sure that the whole document should have only one column. There is another cause suggested by the pop-up box with the error message: an undefined number of columns. That’s a lot of possibilities to check out (not to mention the awful grammar: “if you: The page range might be invalid”). Printing issues associated with a network printer are best handled by your local network administrator or support personnel. Use print scaling (the percentage size to print the final content) set to a number below 10 percent. For example, setting the left and right margins to 5 inches (no room for content to fit on the page). Print to a margin default that exceeds the printable area of the page (can sometimes happen after changing the default printer to a different printer). Print a set sized object that does not fit into the printable region. Print using a landscape setting and the printer driver is set to portrait (or the reverse). Change the margins of the page, and that range is not supported by either the printer or the printer driver. Print to a page size that is not supported by the printer. A valid page range is the slide numbers or ranges using commas or dashes, with no spaces. “This error can appear if the margins are too large or small for the current printer, or if you:” The page range might be invalid. Here’s what you get when you click on “Show Help”: Did you ever get that message when you try to change the size or orientation of a page or the kind of break that begins a section? “Settings you chose for the left and right margins, column spacing, or paragraph indents are too large for the page width in some sections.”
