Print media for use with printers are purposely designed for different uses. Whether printing is to be done using a laser printer, an inkjet printer, or a dot matrix printer, choosing the right print media then becomes essential if the best results are to be expected. Make sure that the print media you choose is something which works well with the printing technology you intend to use. Almost all printer paper or media specifies what kind of printer it is compatible with. Using print media which is not designed for the particular printing technology can yield very unsatisfactory results.
Don't use copy paper in your laser printer. Copy paper dust will eventually attach to the pick up rollers causing excessive wear in turn causing jams.
