Why are some fonts listed with an “unknown” filename?
In some cases, Printer’s Apprentice does show “unknown” for fonts. This usually happens when a software setup program installs fonts and enters the incorrect entry in the Registry. PA reads installed fonts from memory using a Windows API call. It then tries to make a connection with the registry entry to determine the font name. For example, “Arial” is installed. The registry entry is “Arial (TrueType)”. Sometimes a software setup program will make the registry entry “Arial (True Type)” – note the space in “TrueType”. Our software allows for this, but often the difference is significant. For example the font name might be “Arial MT” but the Registry entry is “Arial (TrueType)” – without the MT. The error happens when there is miscommunication between the developers and setup program writers. If the developers give the setup program writers an incorrect list of font registry entries to make, then we get problems. There is a solution: • Open the Fonts window in Windows Controls Panel. •
