I don't have a complicated requirement of qimage - i simply want to be able to print an image as large as possible (not borderless) on a given size of paper - without cropping. I choose between A4 and A5.

I don't understand the significance of 'Fit to page' and 'Fit to Paper'. Initially i used Fit to Paper thinking it means Qimage will print the image as best possible within the printers allowable margins. But choosing Fit to Paper crops the image.

So I now always choose Fit to Page for my requirement - so that the image won't crop.

But what's the diff between paper and a page?

Just to try to keep it simple:

Fit to page: fits the print in the printable area defined by the driver (the printable area is shown over the live view preview).

Fit to paper: fits the print to the full physical paper size, cropping off any non printable margins defined by the driver.

You generally use "Fit to paper" when you are trying to print a scan of (for example) an 8.5x11 sheet of paper and you want to print a "copy" that is the exact same size as the original.  Printing a scan using "Fit to page" will result in a slightly reduced copy because you scanned an 8.5x11 page but your printer can only print on 8.266 x 10.766 on that same size sheet.  Unless you use borderless... in which case "Fit to page" and "Fit to paper" are essentially the same thing.
