3) The font Courier is used as a replacement by the printer when a
font is selected in a point size in which it is not scalable. In the
sizes 8, 9, 10 and 10.5 point, the fonts are printed as bitmap fonts.
Special cases
• The point size is set to Np = 42 (21 point). Proportional and fixed
character pitch ≥ 34:
• If a font with the exception of Courier, Roman or Swiss is selec-
ted, the character for Np = 42 (21 point) is twice as high and
twice as wide as with a point size of Np = 21 (10.5 point).
The following commands use the character pitch set by this com-
mand:
ESC I, ESC Q: set left and right margin
BS: backspace
ESC D: setting of horizontal tabs
If a proportional font is selected, the character pitch for these com-
mands is calculated from the following formula:
Character pitch = 360 / INT (point size * 36 / 10.5 + 0.5) cpi
Downloadable characters
If characters have been downloaded into the printer from the sy-
stem or by means of the copy function, these characters are printed
as follows after defining the character pitch with this command:
