Temporary vs. Permanent Fonts 
Once downloaded, a font is automatically designated as temporary. A 
temporary soft font is deleted from user memory during a printer reset 
or when a Typeface List, a Font Printout or a self-test is performed 
from the printer’s control panel. A soft font can be designated as 
permanent to prevent the printer from deleting it during a printer reset. 
A soft font is designated as temporary or permanent by referencing its 
ID number and using the Font Control command (refer to “Font 
Control Command” later in this chapter).
Note Both temporary and permanent fonts are deleted from user memory 
whenever the printer’s power is turned off.
Switching printer languages (“personalities”), changing resolution, or 
changing the Page Protection setting also deletes temporary and 
permanent fonts from user memory in some printers (refer to the 
appropriate printer User’s Manual for specifics).
An existing font is deleted when a new font with the same ID number 
is downloaded. The new font replaces the existing font (whether 
temporary or permanent).
Deleting Fonts 
There are several mechanisms provided by PCL font management 
that delete soft fonts from user memory. These include commands to 
delete all soft fonts, all temporary soft fonts, or an individual soft font 
by reference to its font ID number (refer to the Font ID and the Font 
Control commands described on the following pages).
