Automatic interface selection
This printer has an automatic interface selection feature that is turned on by default. This lets it automatically
change the interface to IEEE 1284 parallel, USB, or Ethernet depending on which interface is receiving data.
When you use the parallel interface, you can turn the high-speed and bi-directional parallel communications
on or off by using the control panel buttons to access PARALLEL in the INTERFACE menu. (See Menu table
on page 56.) Since the default setting is on for the automatic interface selection mode, simply connect the
interface cable to the printer. Always turn off both your computer and printer when connecting or
disconnecting the cable.
Note
This function takes a few seconds to work. If you want to speed up printing, choose the required interface
manually by using the control panel to access SELECT in the INTERFACE menu.
If you typically use only one interface, we recommend that you choose that interface in the INTERFACE menu.
If only one interface is chosen, the printer will allocate the entire input buffer to that interface.
