Begin Page (BP) - identifies the beginning of the page.

Load Font Equivalence (LFE) - defines the mapping of font local identifiers to coded font Host-Assigned ID.

• Graphic Character Set Global ID (GCSGID) is ignored
• Code page values CPGID:
  • $0000 - no value supplied
  • $0001 to $FFFE
  • $FFFF - CPGID default as specified by configuration
• Font Selection FGID:
  • $0000 - no value supplied
  • $0001 to $FFFE
  • $FFFF is the default for FGID
  • The printer selects a font in a number of ways based upon the requested FGID, FW and font attributes. A list of resident fonts is supplied in the RRL response
  • When an FGID is requested for which no resident font exists in the printer, the printer attempts to satisfy the request through substitution
• Font/Code Page Combinations:
  • The printer allows any combination of font and valid code page without reporting an exception
• Font Attributes:
  • If attributes can not be applied to the requested FGID, the FGID is printed without modification
  • For some fonts, attributes may not be supported. In these cases, no error exception is reported
  • The printer is a coded-font printer; fonts might not be present in the printer for all combinations of pitches and styles requested. In these cases, the printer will select a similar font from those present and can also electronically alter characters to best approximate the desired output
  • The font attribute field is bit encoded. The ignored bits should be set to 0. The following bits are supported:

• Font Width (FW):
  • $0000 - no value supplied
  • $0001 to $7FFE
  • $FFFF - default for a given FGID
  • For typographic fonts, the FW parameter must be used within the IPDS Load Font Equivalence or Load Resource Equivalence commands to uniquely specify which point size within an FGID is being requested
  • The FW parameter for nontypographic type styles is the width of the space character in 1440ths of an inch. For typographic type styles, the font width is 1/3 of the point size converted into 1440ths of an inch. The formula used for this conversion is (point size x 20) /3. All fractional units after this conversion are rounded up, if they are .5 or greater, or rounded down, if they are less than .5.
