The package says they work with Injet and Laser printers but the toner did not fuse properly on the cards so they were smudged. I printed on regular laser printer paper before and after the cards and the project printed fine.
The card quality is excellent. The perforations when you separate the cards are invisible. It prints well with a laserjet (I think this particular stock is ok on both laser and inkjet). But here’s the problem: the Avery template that it uses doesn’t align perfectly. It’s close. But it was just slightly off-center. If you're trying for perfection you either have to play with it till you get it right or accept a slightly off-center result. Maybe the Avery product would have been the same but that hasn’t generally been my experience. I would have purchased Avery but it was out of stock.
