Parallel port
Parallel port lets the user enable or disable the parallel port. If the
port is not being used, disabling it frees allocated memory to be
used to process print jobs.
Note: Optional parallel ports are not available to change in some
network models.
Perform the following steps to change the Parallel port setting:
1. Enter the configuration mode. See “Configuration mode” on
page 3-14 for more information.
The Parallel port (Ready) light comes on solid. The current
Parallel port setting is indicated by the off/on/auto (Press
Button) light. When the light is off, the parallel port is disabled.
When the light is blinking, the parallel port is enabled.
2. Perform a brief button press to select the parallel port setting.
3. Perform a long button press. All lights blink once, indicating the
setting is saved.
4. Exit the configuration mode by turning the printer power off.
Off/on/auto Setting value
❍
Parallel port is disabled. The printer doesn’t receive data
from the parallel port.
●
Parallel port is enabled with a fixed buffer size. The buffer
size is set from a utility such as MarkVision.
Note: This light state is only displayed if the current value
for the Parallel port enabled setting is a fixed
value. The user can’t set the value by pressing the
button to cycle from the off value to the on value,
that is, the button press cycles from off to auto.
✳
Parallel port is enabled with an automatic buffer size. The
printer determines the buffer size based on available
memory and other printer settings.
