Font Header Command

The Font Header command is used to download font header data to the printer.

EC ) s # W [font header data]

Default	=	0
Range	=	0 - 32767

The value field (#) identifies the number of bytes in the font header. The font header fields are described under Font Header Format, later in this chapter.

Note	Two examples for downloading a Font Header are provided under
	Font Header Examples, after the Font Header Format section, later in
	this chapter.

Font Header Format

The font header describes those characteristics of a font which are common to all its characters. Five font headers are included here:

zFormat 0 Font Header for PCL Bitmapped Fonts - This font header, shown in Table 11-2, is not recommended for LaserJet 4 and later printers. It is included in this manual to maintain backward-compatibility with earlier versions of PCL.

zFormat 20 Font Header for Resolution-Specified Bitmapped Fonts - This header replaces the previous bitmap header, and has the added capability to specify a font’s resolution. This font header is shown in Table 11-3.

zFormat 10 Font Header for Intellifont Bound Scalable Fonts - For creating Intellifont scalable fonts which are restricted (bound) to a single symbol set. This font header is shown in .

zFormat 11 Font Header for Intellifont Unbound Scalable Fonts - For creating Intellifont scalable fonts which are not bound to a single symbol set, but are instead composed of a range of compatible symbol collections. This font header is shown in .

zFormat 15 TrueType Scalable Font Header - This new font header supports TrueType scalable fonts (bound or unbound). This font header is shown in Table 11-6.
