Given you want the same header information, I suggest you have that only once, at the start of your file. (I've done that in the attached revised file and corrected cell A3 to include "hard hats" which appeared in cell A49 etc). That way if you need to change the text (or column headers or formatting), you do it in one place.
The trick is then use ribbon Page Layout/ Print Titles and set Rows to repeat at top: to include those 4 rows- it now reads:
$1:$4
Every page will start with whatever is in those rows (use Print Preview to see the headers appear on each page).
It's then just a matter of incremeting the dates then...
To do that, I named cell A5 as "StartDate" (in ribbon Formulas/Name Manager) and cell A6 formula:
= A5
(and likewise for B5/B6) then I copied (only) your signatures rows down. The date from A5 then showed all the way down.
You seemed to be getting 18 signature lines per page (but that may depend on print margins) and wanted doubled sided so I changed the formula in cell A(5 + 2*18)= A41 to become:
=StartDate +1
Now the second date rippled down to the end.
I did then similar for these days/ cells/ formula changes assuming 18 lines per page:
For Cell Changed formula to:
Day 3 A77 =StartDate+2
Day 4 A113 =StartDate+3
Day 5 A149 =StartDate+4
Day 6 A185 =StartDate+5
Day 7 A221 =StartDate+6
so you get the first week of date changes.
I leave you to do these formula changes:
For Cell Change formula to:
Day 8 A257 =StartDate+7
Day 9 A293 =StartDate+8
Day 10 A329 =StartDate+9
Day 11 A365 =StartDate+10
Day 12 A401 =StartDate+11
Day 13 A437 =StartDate+12
Day 14 A473 =StartDate+13
Day 15 A509 =StartDate+14
Day 16 A545 =StartDate+15
Day 17 A581 =StartDate+16
Day 18 A617 =StartDate+17
Day 19 A653 =StartDate+18
Day 20 A689 =StartDate+19
Day 21 A725 =StartDate+20
Day 22 A761 =StartDate+21
Day 23 A797 =StartDate+22
Day 24 A833 =StartDate+23
Day 25 A869 =StartDate+24
Day 26 A905 =StartDate+25
Day 27 A941 =StartDate+26
Day 28 A977 =StartDate+27
Once you've done that, you've only to change cell A5 (and B5 perhaps- both shaded light blue for now) then print double-sided.
Hope this makes sense and works for you.- if so, please remember to mark this Answer as Selected.
