Primary and secondary fonts
The printer maintains two sets of font characteristics which define its primary and secondary fonts. The primary
font is the one it will use by default, the secondary font can be selected instead. This facility enables you to have
two parallel font definitions that you can switch between easily without invoking long escape sequences. You can
select the primary and secondary fonts using PCL commands.
Depending on your model, you can also set any available fonts to be the printer’s user default primary and
secondary fonts using the printer’s control panel. Refer to the User Guide for instructions on how to do this.
The factory default settings for both primary and secondary fonts are Brougham 12 point, 10 cpi Roman 8.
Specifying the primary font
When you specify primary font characteristics you send escape codes with ‘(’ as the second character of the
sequence. This tells the printer that the font characteristic you are specifying applies to the primary font.
Specifying the secondary font
When you specify secondary font characteristics you send escape codes with ‘)’ as the second character of the
sequence. This tells the printer that the font characteristic you are specifying applies to the secondary font.
Selecting the default fonts
To set the primary font settings to those of the printers default font and discard all the software settings you have
made in the meantime, send the printer the following escape sequence:
Esc(3@ (27)(40)(51)(64)
<1Bh><28h><33h><40h>
To set the secondary font settings to those of the printers default font send:
Esc)3@ (27)(41)(51)(64)
<1Bh><29h><33h><40h>
Switching between the primary and secondary fonts
To select the primary font as the font for printing send the printer the SI control code:
SI
(15)
(0F)
To select the secondary font as the font for printing send the printer the SO control code:
SO
(14)
(0E)
Criteria for font selection
The printer will try to match your stated font requirements as best it can with the fonts available to it in the three
font locations. In most cases you will be specifying a font you know to be present in one of the locations and the
resulting printed text will appear exactly as you envisaged. However, if you specify a particular combination of
font characteristics that is not possible, the printer will produce the closest possible match that it can by satisfying
the following specifications in the order: the symbol set, spacing type, pitch (for monospaced fonts), the height,
the stroke weight and the style. The meanings of each of these are explained in the following sub-sections.
Likewise, if you simply specify a font attribute that is not available, for example if you request a Utah Light font
when only Utah Medium and Utah Bold are available in the font locations, the printer will simply ignore the
requirement (light stroke weight, in this case) that it cannot fulfill.
Symbol set
The symbol set is the list of symbols that constitute a particular font. Normally symbol sets contain lower and
upper case letters, numbers, punctuation marks and a selection of other commonly used symbols. Some symbol sets
are designed for specific needs, for example, for generating text with mathematical expressions. The symbol set
has the highest priority of all the characteristics you specify when you designate the font you require. If the symbol
set you choose is available, but not in conjunction with any of the other characteristics you specify, the printer will
satisfy your symbol set request at the expense of the rest of your designation and the text printed out may well look
completely different from what you expected to see.
