Use scrap paper if you are printing a draft or rough copy of a document. Pick generic 20-lb.
Coated papers prevent that saturation.
Check your printer manual before using heavy stock. The manufacturer usually suggests a weight limit. Even under the limit, though, stiffer media tends to jam. Linens, other textured papers and most recycled papers work poorly in both ink-jets and laser printers. Although printer manufacturers would like you to believe that you will get the best results using their brand of papers, this isn't always the case.
