SFNT
height parameter is omitted, the printing system sizes the font to the height of the current
font. The following example displays a range of font heights.
You can assign any number from 1000 to 65535 as a temporary font-number, as long as
you do not duplicate the number of a bitmap font or a font number already in use. If the
number matches one already assigned to another font, the printing system ignores the
SFNT command.
symbol-set uses HP PCL matching code to change the font's symbol set. Unsupported
symbol set values, if specified, are ignored.
compression squeezes or expands characters in the horizontal direction.
Compression = 0.3 Compression = 1 Compression = 3
shear imparts a slant to the characters: forward if the angle value is positive; backward if
it is negative. Zero gives upright characters.
Shear = 0
Shear = -1 Shear = 1
Changes made with SFNT to a scalable font in its height, symbol set, compression, and
shear remain effective until another font selection command is encountered. To retrieve
this scalable font later, use the FONT command.
