That is funny because I have a HP photosmart 7150 which prints perfectly on card or paper.
But I tried to print on a slightly heavier grade paper, the only other difference being it was orange in colour.
The printer began taking in the printer but then stopped while it's light shone on the paper, the paper then went further in, but it did not print.
I then got the message up 'paper jam, don't try and pull it through from the front, remove from the back of the printer'
I cancelled the print job, pressed the error button, and the paper came out of the printer from the front.
Iv'e tried evertything it still refuses to print on this paper160/gm2.
