Printing from ipad

Hi everyone

I am trying to print a jpeg that’s 15x15cm big from my iPad. Unfortunatelly, the iPad always resizes the image to fit to the media size. So for example, if I choose A4 as Media size, it makes my image bigger. If I choose a smaller media size like envelope, it makes my image smaller.

I would like to print my image on a A4 paper and keep it the size of 15x15 cm.

When printing from my laptop, there’s a button I can unklick that sais “scale to fit media”. This would of course solve my problem, but from the iPad I have only limited options to configure the printer like media size, tray and paper quality, but no button saying scale to fit media.

I have a brother printer that’s connected to the same network as my iPad. I already downloaded the brother app iScan, but inside the app there is no option to change that scale to fit media nuisance…..

Can anyone help me please? It’s driving me mad!
