Since a PhotoSmart is presumably designed to print on photo paper, I can't
imagine that it wouldn't print on card stock, but your manual should give
specifications for paper thickness and other physical properties
accommodated by the printer.
You can see a chart of paper specs at
http://h10025.www1.hp.com/ewfrf/wc/...en&dlc=en&cc=us&product=3655575&lang=en#N1746
According to the chart, the printer will handle up to 110-lb. index, but the
only card sizes provided for are 3 x 5, 4 x 6, and 5 x 8. The limit for
plain paper (Letter, legal, and A4) is 24 lb.
