2-8 Installation
Never connect the laser system through a manual switch type A/B switch box. If
connecting an additional laser system or other printer to the same computer, we recommend
the installation of an additional parallel port into the computer.. This creates electrical noise
which can cause an engraving problem or can damage the laser system and/or the computer’s
electronics.
Never use any device that is installed between the computers parallel port and the
parallel port of the laser system such as a ZIP drive or parallel port CD-ROM drive. This
can not only damage the laser systems electronics but it usually will not work. Again, install an
additional parallel port for other peripheral devices.
