CHAPTER 2 "PCL" - 38 

5.1.9.  Downloadable fonts 

You can buy diskettes containing fonts which can be copied directly to the printer using t he DOS COPY 
command. You can also design your own fonts and download them to the printer.  

One disadvantage of downloaded fonts is that they reside in the printer’s RAM memory. The printer also uses 
this memory for composing the text and graphic output that it prints on the page. If the memory contains too 
many fonts the printer may run out of memory. Since downloaded fonts are stored in the printer’s RAM they are 
lost when the printer is switched off, and you must download them again before you can use them. 

5.1.10.  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 s elected 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.  

5.1.11.  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. 

5.1.12.  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 applie s to the secondary font. 

5.1.13.  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> 

5.1.14.  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) 

5.1.15.  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 any of the 
three possible 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 following order:  symbol set / spacing type / pitch (for 
monospaced fonts) / height / stroke weight / 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.
