Using the built-in print dialog through the user controls results in slow and resource-intensive performance when printing. I've tried several PDFs and all have the same behavior. The print preview is also slow and resource heavy, I guess because of the size of the rendered page bitmaps. Is there a way to improve performance? I looked over the forum page here:

Print functionality thread

Using the first example (the short printing example), the pages render quickly (but of course don't all account for things like page rotation). Also, when you print to Microsoft XPS (an .XPS file output), the file size is reasonable. Using the full-blown code where it accounts for page rotations and such, the performance is slow and the output XPS files are on the order of 8-10X the file size (from my tests) but the quality is no better. Why the size differential? Maybe there are too many transformations or unnecessary scalings that are happening in the built-in printing code?

Thanks for your help.

PdfPrintDocument can be used for printing in WPF too
