Hi M,

The error message you are receiving usually occurs when there is a problem with the print area or print settings in one or more of the worksheets in your workbook. Here are a few things you can try to resolve the issue:

1. Check the print area: Make sure that the print area is set correctly for each worksheet. To do this, select each worksheet in turn and go to the Page Layout tab. In the Page Setup group, click on the Print Area dropdown and select Set Print Area. If there is already a print area set, make sure it is correct. If there is no print area set, select the cells you want to print and then set the print area.
   
2. Check for hidden rows or columns: Sometimes hidden rows or columns can cause issues with printing. To check for hidden rows or columns, select the entire worksheet by clicking on the Select All button (the box at the intersection of the row and column headers). Then, go to the Home tab and click on the Format dropdown in the Cells group. Select Hide & Unhide and then choose either Hide Rows or Hide Columns. If any rows or columns are hidden, unhide them and try printing again.
   
3. Check for page breaks: If you have manual page breaks set in your worksheets, this can cause issues with printing. To check for page breaks, go to the View tab and click on Page Break Preview. If you see any blue lines indicating page breaks, you can adjust them by dragging them with your mouse. You can also remove them by going to the Page Layout tab and clicking on the Breaks dropdown in the Page Setup group. Select Remove Page Breaks.
   
4. Check for merged cells: Merged cells can also cause issues with printing. To check for merged cells, select the entire worksheet and go to the Home tab. In the Alignment group, click on the Merge & Center dropdown and select Unmerge Cells. If any cells are merged, unmerge them and try printing again.

I hope one of these solutions works for you. Let me know if you have any further questions!
