IBM 1220 Parallel Mode 1, Parallel Mode 2

177
Parallel Mode 1
Purpose:
To control the pull-up resistors on the parallel port signals. This menu item is useful for personal
computers that have open collector outputs on the parallel port signals.
Values:
Parallel Mode 2
Purpose:
To determine whether the parallel port data is sampled on the leading or trailing edge of strobe.
Values:
PCL SmartSwitch
Purpose:
To configure the printer so it automatically switches to PCL emulation when a print job received
through the parallel port requires it, regardless of the default printe r language.
Values:

Printer Language; PS SmartSwitch
On Disables the resistors.
Off* Enables the resistors.
On* Samples parallel port data on the leading edge of strobe.
Off Samples parallel port data on the trailing edge of strobe.
On* Printer examines data on the parallel interface and selects PCLemulation if the data
indicates that is the required printer language.
Off Printer does not examine the incoming data. The printer uses PostScript emulation to
process the job if PS SmartSwitch is On, or uses the default printer language specified in the
Setup Menu if PS SmartSwitch is Off.
