Hello I had a HP 1320 laserjet hooked up to a mac running 10.2.8. I recently upgraded to Mac OS 10.4.9. It worked fine before but since the upgrade images wont print correctly. Instead of printing the image it will just spit out a bunch of letters and number and use up all the paper in the printer. I tried printing these same images to another printer and had no problem at all. I suspect that it is a driver issue since upgrading. I have the driver disk and also went onto HP's website to download the latest drivers. This still did not fix the problem.
