Abstract

Existing typestyle numbers do not allow a way to distinguish multiple versions of the same typestyle. Multiple versions of the same typestyle occur frequently due to printers supporting the same font with multiple character set and font width variations.

Distinguish Multiple Versions of a Typestyle Using Typestyle Identification

       Existing typestyle numbers do not allow a way to
distinguish multiple versions of the same typestyle.  Multiple
versions of the same typestyle occur frequently due to printers
supporting the same font with multiple character set and font width
variations.

      A printer might support a font element with a version of
Courier 10 (typestyle 11) that contains characters from the Character
Set and another version of the same typestyle on a different font
element that contains characters and symbols from the Characters and
Symbols character sets. Previously, the Printer Function Table had to
define two different typestyle definitions (each with a different
typestyle number) to support such font elements.  This forced the
user to enter a non-registered typestyle number (e.g. 65) to select
one of the two fonts.  This prevented the user from correctly
interchanging the Courier typestyle (typestyle 11) to other
applications that support Revisable-Form Text (RFT).  Since an
application would receive a non- Courier typestyle (e.g., 65), the
application might not select a Courier 10 font and so the document
would be printed with the wrong printer font.

      The concept of a typestyle id was defined to consist of a
typestyle number and an optional identifier (A-Z).

      In order to maintain compatibility with previous products, the
optional identifier is not stored as part of the...
