I have set up a project at 300 ppi in photoshop and the printer wants a 600dpi pdf. How can I do that please?

In Image Size, uncheck "resample" and change ppi to 600. This doesn't change the file in any way. Then save out a new PDF.

You need to realize that ppi is just metadata. It's not a property of the file. It's just a way to translate pixels into a physical print size. Pixels per inch. It means exactly what it says.

The bigger you print your file, the lower the ppi number, and vice versa. Print size determines ppi.

So if what the printer is really saying is that your file doesn't have the necessary pixel resolution, you can't "fix" that. You need to make a new file with more pixels.
