What is the .SFB File Extension?

.SFB File Extension Description:

Fonts are often used to refer to typefaces. However, the difference is that fonts store not just the specifics of a typeface, but also the size. Fonts contain all the characters of a certain typeface. The typeface describes the appearance and the spacing needed for a specific set of characters. A typeface stores the specifics for printing and showing how letters, numbers, punctuations and certain symbols should be printed or shown on screen. Fonts store typefaces, which are saved in specific sizes. A Times New Roman font in size 12 is stored separately from Times New Roman font in size 9. In some cases, fonts even store the different styles applied to the fonts. The bold, italic and underlined versions of typefaces can be stored as separate font files.

Files with the SFB file extension are called soft fonts. These type of fonts need to be transferred from a separate memory to the printer. Printers have their own resident fonts. Resident fonts are those fonts that can be printed out by the devices. If a document or file uses a font not supported by the printer, it cannot be printed out as it is shown on screen. On some instances, the software monitoring the printer will replace an unsupported font with a residential font to be able to show the text.

Soft fonts with the .sfb file extension are created using Printer Command Language. (PCL) This programming language was developed by the Hewlett Packard Company to write specific processes for their printing devices. The language was later adopted as a standard for the industry. PCL is used to create soft fonts with the file extension SFB so that the printer can access them.

Files with the SFB file extension are made up of descriptions of the font and of the character. The font descriptor tells the printer and its inherent process how the font should be read. Character descriptors tell the software how each individual symbol, letter, number of punctuation mark should be interpreted. The character descriptor tells the printer how to position and create the shape of the character followed by an image of the character it is describing.

Unlike resident fonts, soft fonts with the SFB file extension can be added to or removed from the resources of the printer. Resident fonts are needed by the printer to create documents. Files with the file extension .sfb can be created by font editor software, which allows users to create their own kinds of typefaces and fonts.
