Set print area as multiple ranges

[TPDave]

Hi All,

I've uploaded a sample sheet which will hopefully be easier. I need my print area to be rows A2:H2 (headers) and all the rows (from A to H) which have an entry in column M but not in column P. So for the attached example I would need the print area set for the following:

A2:H2
A18:H22
A26:H29
A32:H34

I've tried doing a range with multiple arguments but it breaks once I move away from set limits and make them variables so am very confused!

Any help would be greatly appreciated. Thanks
