7.3 HOST INTERFACE
There are two types of host interfaces: the RS-232C interface and the printer interface.
Select either using the I/F SELECT switch. When the PG-FP3 is started, the software identifies the switch setting.
Note that once an interface has been selected, it cannot be changed until power is turned off and then back on again.
7.3.1 Printer Interface Specifications
The printer interface uses the parallel port provided on most personal computers as standard. Some parallel ports,
however, do not support bidirectional communication and ECP mode. To find out whether a port supports bidirectional
communication and ECP mode, consult the manufacturer of the personal computer. The printer interface
specifications, which conform to IEEE 1284-1994, are as follows:

If communication settings are not correctly performed, the Connection Port error dialog box may open. If this
happens, check if the Connection Port setting is correct.
The specifications of the interface connector and specifications of the interface cable are given on the next page.
Note Be sure to use a host computer that supports ECP mode.
