English to Greek Tech/Engineering Computers (general) Printer User Guide

I have found that monospaced is σταθερού πλάτους / μονού διαστήματος, but I cannot find anything about nonscheduled.

Context (in the explanation of the settings for the printer):
Font pitch refers to the number of fixed-space characters in a horizontal inch of type. For nonscheduled mono spaced fonts, the pitch is displayed, but cannot be changed.
