Best used in draft mode especially for double sided printing. I buy this whenever its on hand for the kids to use for school projects whether in the printer on for drawing. Its a bit thin so I wouldn't use it for double sided if you are doing more than just printing text. It's not so great for printing pictures or items with a lot of ink.
Great paper for all around business and / or personal use. We've used this for several years in laser and injet printers as well as fax machines. NEVER had a jam.
