wifi printing error in iOS 14.6

i'm experiencing a repeatable bug on my iphone where i print an image to one of my two printers and when the image comes up i the print dialog it is properly sized but it then scaled it up slightly so the margins are lost.

so if you have an image of a document it will mot print with the margins because these are lost when it zooms in. this happens on any image printed on the iphone.

and you can actually see it happen when it come up in the print dialog at proper size and when zooms in while you are looking at it.

any fixes?

THANKS
