5.2.9 Setting image quality and toner saving
To set print and image quality, open the Screen panel of the printer driver
Plug-in.
In this panel you can set the [Screen Frequency], (measured in lines per
inch, lpi). Higher values at screen frequency yield a finer raster, but allow
less grey levels to be distinguished.
[Screen Angle] allows to adjust the angle (measured in degrees,°) in which
the raster lines are applied against a virtual horizontal line. In general, you
don’t need to change the default setting.
[Print Quality] can reduce the amount of used toner in two steps for e.g.
previews of documents to print.
For detailed information about image and print quality see section 6.3.9
"Screen".
