Note: The Series 500 Model 520 printer is designed to
print approximately 50,000 ft. of paper prior to print head
replacement. The actual print head life will vary, however, with
usage. If you expect to do a lot of printing, we recommend that
you consider purchasing a heavy duty printer such as one of the
HP
impact printers.
