Features missing in QPrinter (which are not easily added without at 
least extending QPrinter and implementing QPrintEngine and 
QAbstractPrintDialog):

* Print preview
* Printing a list of pages (such as 1,4,6-8) or the current page
* Custom margins
* Straightforward printer options (try clicking "properties" for a 
printer in the print dialog of the Qt assistant program, and doing the 
same in kolourpaint)
* "Special" printers (like Send Fax via KFax) independent of eg: CUPS
* Integration with the KDE print management system (ties in with the 
above two points)

I guess it comes down to how much value you place on these features.
