Printing from Risc OS 6

After an upgrade to Risc OS 6 I seem to have lost printing, so downloaded PrintPDF. It sits on the right hand end of the icon bar, but does not seem to be working.

The problem may be something to do with GhostScript. How can I check if it is installed?

Would a return to Risc OS 4 work? I only need to use TextEase, which is the original version from SoftEase, not the recent release.

I am running Virtual Acorn on MacBook Pro macOS 10.11.6

Any help gratefully received.

How did you manage to print before with RO4?

Wouldn’t you have run the printing App !Printers
