How do I save a PO as a PDF in a local file without spool?

[GWIN13]

ME22N - I have the option to view PDF PO, toolbar GOTO then PDF PREVIEW. 

So I have this on my screen and now I want to SAVE as PDF on my local file:

Print icon is greyed out and CTL&P doesn't work, is there another way without the 100 steps to spool request (needs to be simple & quick)? 

Any help would be apricated.
