IEEE 1284 Parallel Interface
Terminating Resistor Configurations
V6 Controller Board
For parallel interface configurations, the printer is equipped with 470 Ohm and
and 1K Ohm terminating reistors on the controller board. These are suitable
for most applications. See
Figure 10.
If the standard terminating resistor pack is not compatible with the particular
interface driver requirements of the host computer, other RP1 and RP2 values
may be required. 220 Ohm and 330 Ohm alternate terminating resistors are
provided with the printer. If you install the 220 Ohm resistor, you must also
install the 330 Ohm resistor. Possible terminating resistor combinations are
shown below.
