Trying to print from Safari PDF but can't see any page numbers
I have just opened a 700+ page PDF document in Safari and need to print odd pages here and there but I can't see any page numbers displayed when I scroll through the document. When I display the same document on an iPad the page numbers change as I scroll through but on my iMac (using Safari 10) they don't appear at all - and 700+ pages is a lot to get wrong! Any clues how I can switch on 'Display page number'?
iMac, OS X El Capitan (10.11.5)
