What types of paper and media should I avoid using in the HP LaserJet P1102?

Do not use paper or print media made for inkjet printers, as HP LaserJet products use fusers with extreme heat that could damage the product. Additionally, avoid envelopes that are wrinkled, have clasps, snaps, windows, or coated linings, and do not use glossy or coated paper designed for inkjet products. Using unsupported media may cause poor print quality, increased jams, and premature wear not covered by the HP warranty. (Page 44-45)
