The point size is determined by means of the parameters Lp and
Hp:
Np = Lp + Hp * 256
point size = Np * 0.5
Refer to the following table for details:

1) No change: if the point size assignment of a previous font
scaling command is still valid, this point size is used. If the point
size assignment is deleted, i.e. no point size is selected, the font
is printed in the currently valid font size and the current charac-
ter pitch (cpi).
2) The size of a font scaled to 9 points has the same appearance as
that to a scaled to 8 point.
The table below gives the assignment of selected character pitch Pn
to the bitmap fonts used by the printer if scaling is not possible:
