Cannot Print PDF documents with Acrobat

Hi there, I work in IT support at a primary school,

We use a lot of pdf files and are constantly printing them. Recently a lot of the teachers/admin staff's laptops and desktops have stopped being able to print PDF's through adobe acrobat. I have reinstalled printer drivers, tried printing as image and even fully reimaged some machines and nothing works still.

I can print PDF's fine through any other PDF reader no problem.

Any advice?
