Special cases
Point size is set to Np = 42 (21 points). Proportional or fixed
point size Pn ≥ 33.
If a font other than Courier, Roman or Swiss is selected, the char-
acter (Np = 42, 21 points) is double width and double hight in
reference to point size Np = 21 (10.5 points)
Fixed character pitch: 5 ≤ Pn ≤ 33
A character for Np = 42 (21 points) is double hight in reference to
point size Np = 21 (10.5 points)
The following commands use the pitch set by this command:
ESC X: Set left and right margins
BS: Backspace
ESC D: Set horizontal tabs
If proportional spacing is selected, the pitch is calculated from the
following formula for these commands:
Pitch = 360/INT (point size * 36/10.5 + 0.5) cpi
Printing in UTILITY
If a proportional font selected (Pn=1), the printer substitutes the
Utility font by the chosen font via menu in letter quality. Is UTILI-
TY selected in the printer menu it is substituted by Courier.
If a fixed pitch is selected, the pitches and point sizes are used given
in the table of bitmapped character sets above.
If no point size is entered in this command (Lp=Hp=0), the point
size is selected which was defined previously with this command.
If the point size is deleted or not set, printing takes place with a size
of 10.5 points.
