Set Rows to Repeat at Top of Multiple Worksheets
If you right click on a worksheet in Excel, you'll be able to 'Select All Sheets' and perform many editing tasks on all worksheets simultaneously. However, under Page Layout . . . Page Setup . . .on the Sheet tab, you will not be able to enter a range in the Print titles section for, "Rows to repeat at top" - it is grayed out, disabled. This setting makes column headers in one or more rows, repeat on each page of a worksheet printed to a PDF or hard copy.
Gord Dibben posted Visual Basic code here which will allow you to designate a range of rows to be entered in the "Rows to repeat at top" field on all worksheet.
Press ALT + F11 to enter Visual Basic and enter the below vba code in a new module [right click on the workbook name in the project list and select Insert . . . Module]. Designate the rows on the line which begins, "ws.PageSetup.PrintTitleRows", preceding each row number with a dollar sign. Press play and the row range will be entered for each worksheet.
