convert active sheets to pdf

Hi,

I have either 2 or 3 or 4 sheets that are being activated depending on the dropdown filter chosen
and I want these active sheets to be converted as 1 PDF


Here are the 3 scenarios with their Sheet names:

Scenario 1:
Printout_Front (to be very hidden at the end)
Turbine1

Scenario2:
Printout_Front (to be very hidden at the end)
Turbine1
Turbine2

Scenario3:
Printout_Front (to be very hidden at the end)
Turbine1
Turbine2
Turbine3
