package, installed on the GNU/Linux host, is used by the PDF printing renderer to
get the best matching installed font as substitute for non-embedded fonts in the PDF
The PDF "Standard 14 fonts" aka "Base 14 Fonts" are never embedded. Every PDF renderer is required to provide these fonts, either directly or via appropriate substitutes. Current substitutes are shown in the Admin Web App, About Host Packages section.
When a PDF document contains non-embedded fonts that are not from the Standard 14
fonts, the substitute fonts selected by
fontconfig may not be the
same as the fonts used to create the PDF, and so rendering may not be correct.
Therefore, it is wise to install additional fonts, especially the much used
Microsoft True Type Core Fonts with Andale Mono, Arial, Comic Sans MS, Courier New,
Georgia, Impact, Times New Roman, Verdana, etc.
