HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part II

EN SD, Standard Font Definition 23-71
Kind 4: Height
For proportional fonts, the height characteristic defines the font point
size (the height of the character cell). (Fixed-spaced fonts ignore
height; the point size is calculated using the font pitch.) There are
approximately 72 points in an inch. Note that with the font definition
command (SD or AD)., you cannot create tall, skinny characters or
short, wide characters; the character aspect ratio is preserved.
Kind 5: Posture
Posture defines the character’s vertical posture. The default posture
is upright.
Kind 6: Stroke Weight
The stroke weight characteristic defines the line thickness used in the
font’s design. The default stroke weight is medium. When relative
sizing is in effect, changes in P1 and P2 cause the relative stroke
weight to change in relation to the change in P1/P2. If the aspect ratio
of the P1/P2 rectangle is maintained as P1 and P2 are moved, a
medium stroke weight font still looks “medium” after it is enlarged or
reduced.
Note Available stroke weights are the same as those available within PCL.
