    Guidelines for selecting and using paper 14 Recycled paper As an environmentally conscientious company, we support the use of recycled paper produced specifically for use in laser (electrophotographic) printers. While no blanket statement can be made that all recycled paper

Depending on your printer model, material thicker than 0.30 mm (0.012 in.) may present feed reliability problems, and material thicker than 0.17 mm (0.007 in.) may reduce print quality. Contact your supplier to determine the weight of any card stock

    For lighter card stocks, we recommend grain long to reduce potential curl problems. Curl may decrease the ability of the form to move reliably through the printer . Most printers feed paper short edge first. If your printer supports larger paper sizes, such as 11 x 17 in. or A3, it
