Laser printing in general will hold up better to contact with oils than inkjet printing. It's hard to classify inkjet or laser printed labels as "oil-proof" because the print is exposed and not sealed by some kind of laminate or protective coating. Prolonged exposure to oils could eventually degrade the print quality, even with laser printed labels.
With that being said, laser printing is considered to be much more durable than inkjet printing, and laser printed labels should hold up well to incidental contact with oil. The HP Color LaserJet models referred to earlier in this thread should work well for your application, as long as you are using our
weatherproof polyester laser label material. To ensure the best results, please set the media/paper setting to something like photo, glossy, or labels.
