Use each printer default paper size
In the printer dialog the paper size is always the latest size chosen by the user, no matter which printer I'm using.
Let's say I have a regular printer where I print A4 sheets and a label printer where I print 10x15 cm sheets. These sizes are defined in each printer setting as their default size: Printer properties>Page setup>Paper size.
If I print to the label printer after using the regular printer I have to change size; and the other way around.
Expected behaviour: it should use each printer default size and ignore the size used when using another printer before. This is the behaviour I see also in Windows.
I'm describing a bug which existed in Linux for years and I never cared for opening an issue before (thinking somebody would have fixed meanwhile). Do you agree that it's a bug or I'm missing something?
