TrueType and OpenType fonts

OpenType is an enhanced form of TrueType technology that is designed with Unicode in mind. OpenType is the font technology that IBM® is using to support presentation of Unicode. TrueType fonts contain characters to support language and scripts from around the world. Presently, over 52 000 glyphs are contained in a single type style. Subsets of this data are also available to allow a smaller file size to support certain geographic areas.

TrueType fonts are supplied in option 43 ("Additional Fonts") of i5/OS. They are provided as stream files in the TrueType (OpenType) format.

TrueType and OpenType fonts reside in one of two integrated file system directories:

When searching for fonts, the UserData path will be searched first followed by the ProdData path.

You must use the FONTNAME DDS keyword to select the TrueType fonts. Unlike the other supported font resources, the TrueType fonts are referred to by their full font name, not by the file or object name.

The following fonts are supplied in option 43 ("Additional Fonts"):

TrueType fonts can only be used with printer files that have a device type of *AFPDS.

If you need the additional function provided by linked fonts or you want to capture fonts in the printer, then you need the Infoprint Fonts for Multiplatforms V1.1 (5648-E77) licensed program (or equivalent). This product contains fonts as well as the font installer utility.

When the Infoprint Fonts for Multiplatforms V1.1 (5648-E77) licensed program is installed, it changes the way that fonts are searched for and located. The Infoprint Fonts for Multiplatforms V1.1 (5648-E77) licensed program builds a resource access table. The resource access table contains a mapping of the full font name to a system specific file name. Fonts are now searched for based on the information contained in the resource access table.

1 The Monotype Sans Duospace Ext B font is an extension of the Monotype Sans Duospace WT SC font. The Monotype Sans Duospace Ext B font is linked to the Monotype Sans Duospace WT SC font by the resource access table that is supplied with i5/OS Option 43 - Additional Fonts. This linking makes all the characters from both fonts available to documents that specify the Monotype Sans Duospace WT SC font name.
