QMS 2060 Reference page 125

If you do want to reconfigure the interface ports for specific emula-
tions (or if you need to return the printer to ESP mode), use the
printer's control panel (the Administration/Communications menu).
Configuring the printer through the control panel is described in chap-
ter 4, "Printer Configuration," of this manual.
The ability of the printer to produce halftones allows you to add
scanned images or halftone graphics to your documents. This section
will explain some of the options available on the QMS 2060 for half-
tone printing.
Continuous tone scanned images have to be converted to dot pattern
images on a laser printer. Laser printers, like printing presses, only
have the ability to print patterns of dots controlled by turning on and
off the laser. Because of the limited resolving power of the eye
halftones appear as continuous tone images. For example, if you hold
a newspaper photograph very close to your eyes you can see the
halftone dots.
Halftone characteristics can be changed by settings available on your
QMS 2060 Print System. The following factors can be used to adjust
the halftone characteristics of your documents.
Printer resolution
Screen frequency and screen angles (Halftone types)
Smoothing
There can be some side effects to changing these factors. Factors
such as the number of gray levels, printer performance, and scanned
image quality can be affected.
