I got a brand new HP Compaq desktop computer and I have an older 4700n HP laserjet printer. After the last Windows update, I started getting thick Vertical White Stripes on images when printing pictures. We rolled back the update but it didn't improve.
As a note, the issue happens when trying to print a picture (or series of pictures) by right-clicking and choosing "print", then going through the "Print Pictures" utility. The issue doesn't seem to happen when going through the print option in the Picture viewer, or for text documents.
