There seem to be two issues

• printing from mobile devices applies the breakpoints suitable for the device but (depending on the printer configuration) puts this on an A4 page which looks suboptimal (and different from what happens when printing from a desktop device to A4)
• apparently the skin switched while(?) viewing the donation confirmation

The first problem is valid and should be addressed, I create a ticket for it: T182664

The second problem can probably attributed to a reload of the page while not sending a (valid) skin cookie. However, I can not think of a scenario in which our behavior causes this - the donation confirmation or the print view in particular do not perform any interaction with the skin service beyond that of any other page. Maybe it is a client bug, forgetting all cookies after printing? I don't see a way to reproduce (no test device) or resolve this.

@BullerMia Kannst du das auch reproduzieren? Auf welchem Gerät tritt das auf?
@gabriel-wmde Any ideas? Otherwise I suggest we leave this rest.

@Pablo-WMDE i could not reproduce the second problem either. It worked fine for me (iphone5). I think the originally used device was an Apple iPhone 6, Betriebsversion Version 10 and Browser Safari.
