Cardstock question.

[penguinsane.livejournal.com]

Is there a technique to printing on card stock? I have a HP Photosmart C-6180 All-in-One printer and am having a hard time feeding it. It feeds right, hesitates like it's thinking about printing, but spits it out and proceeds to print on the next page (which is just plain printer paper).

I threw away the package wrapper, so I forget what weight it is, but it's just cheap, simple colored cardstock from Walmart's office supply section. Any help would be greatly appreciated!
