Thanks again...but, and I am not a nasty guy, odd to have a print size drive an image size estimate without being able to print the image that size.
I went through every post in the Print It section and was happy to see it give me some hope of running Print It under windows 10 and with a current version of paint.net. However my attempt to download was blocked by my anti-vurus software (Bitdefender). Sometimes these things "clear up." I will persist.
