To ensure all columns print on one page without adjusting their widths, what must be done?

To ensure that all columns print on one page without needing to adjust their widths, changing the print settings to fit all columns on one page is the effective solution. This option typically involves adjusting the scaling settings in the print dialog of the spreadsheet software. By selecting the option that allows for fitting all columns to one page, the software automatically resizes the printout to accommodate the specified number of columns within the page margins, maintaining readability without altering the actual column widths in the document.

Setting a print area manually allows you to define which parts of the document will print, but it does not directly address the issue of column widths or ensuring all columns fit on one page. Decreasing the font size can impact readability and does not guarantee that all columns fit without adjusting widths. Printing only visible cells might exclude relevant data and doesn’t address the column fitting issue. Thus, opting to adjust the print settings to fit all columns on one page is the best method for achieving the desired outcome.
