Well, KPrinter (and Qt3's QPrinter) provides methods which allow you to 
get and set the left, right, top and bottom margins.

QPrinter provides paperRect() and pageRect(), the latter being the 
printable area.  There is no way to set the margins yourself, but you 
can use setFullPage() to change the origin from the top left of 
pageRect() to the top left of paperRect().

The reason setting the margins doesn't really make sense is that 
printers have an area that they can print on (which may be the full 
page for some printers), and no amount of software settings is going to 
change that.

I'm not sure what applications are currently setting the margins for - 
possibly just to change the co-ordinate system.  However, you can do 
this using QPainter::translate().
