Hi,

When I use a image as backgroundImage of a UltraGridPrintDocument's header, the printed grid in PrintPreviewDialog became broken, leaving blanks where it should be cells.

Can you reproduce this in a small sample project and post it here so we can take a look?

Besides, when I print the grid in PrintPreviewDialog, the image in header's background is printed in very low resolution, like mosaics. I tried with many images and it seems that only afew could be printed properly. Is there something related to the size of the image that I miss?

It sounds to me like your images are getting stretched. Most printers use a much higher DPI than the screen. So an image on-screen may appear very large, but when printed to a printer, it becomes much smaller. So if the image is stretched on the printer, then it will not look good unless the image is stored with a very high DPI setting.
