After further investigations about the KDE/Qt print mechanism I found out that the printing problem with digikam/printwizard is a Qt problem. The Qt postscript driver is very poor and can only create postscript level 1. The resolution of the image is not the problem. It seems that the image is embedded with the original size. The larger the source image the larger the postscript file. But many printer driver use ghostscript to create raster files and the postscript created with Qt is very inefficient. Preview and further processing takes very long. Gimp uses gimp-print or gutenprint, which can create a postscript level 3 file. Ghostscript can process this file much much faster when viewing and printing. I think there is nothing to be done.

Maybe you can try the program photoprint (http://www.blackfiveservices.co.uk/photoprint_news.shtml). It can be called from digikam context menu "Open with ...". It uses gutenprint directly and prints very fast.
