If you are printing on a HP laser printer in Debian, and you try to print a test page that only produces the following output:
PCL XL Error
SubSystem : KERNEL
Error: IllegalAttribute
Operator: CloseDataSource
Make sure you install the following packages:
# apt-get install hplip hpijs-ppds
Once you have completed that, you should find that you are able to restart cups, and set up you printer normally. I certainly hope this helps some people who may be beating themselves over the head repeatedly.
