QPrinter/KPrinter default resolution

[Lubos Lunak]

 Hello,

 QPrinter/KPrinter default to QPrinter::ScreenResolution as the printer mode, 
and KPrinter's setUsePrinterResolution() defaults to false. This leads to 
using relatively low resolution when printing, which is especially visible 
with images.

 I'd like to suggest defaulting to setUsePrinterResolution() being true, and 
printer mode being QPrinter::HighResolution. Alternatively (for KDE4 
only :-/ ), removing the default value for the printer mode, so that the app 
developer must choose and will know about this, and having using printer 
resolution as another argument for ctor, or making it another printer mode. 
This alternative would mean apps for KDE3.4 would have to be checked and 
changed manually, like in http://bugs.kde.org/91644 .

 Would there be any reasons to default to such low dpi values like 
QPrinter/KPrinter currently do? I can think of images in image viewers being 
printer smaller with higher dpi, but those usually have adjusting the image 
size anyway. Would this also affect e.g. text editors?
