Kommandos

Da bei der Beschreibung der IPDS-Kommandos viele Fachbegriffe notwendig werden, die sich nur sehr schwer in verständliches Deutsch übersetzen lassen, sind die nachfolgenden Seiten bewusst in Englisch abgefasst. Dadurch wird auch der Zugriff auf die weiterführenden IBM-Handbücher um vieles erleichtert.

Following command sets are contained in the IPDS architecture:

  •   Device Control - to initialize the environment, to manage resources, to handle the acknowledgement protocol
  •   Text - to present text information in a page, an overlay or a page segment
  •   IM Image - to present images in a page, an overlay or a page segment
  •   IO Image - to present images, compressed images and grayscales in a page, an overlay or a page segment
  •   Graphics - to present graphics in a page, an overlay or a page segment
  •   Bar Code - to present bar code information in a page, an overlay or a page segment
  •   Page Segment - to store and present text, image, graphics and bar code information
  •   Overlay - to store and present text, image, graphics and bar code information
  •   Loaded Font - to load font information


Device Control Command Set

$D6AF

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

$D64F

Deactivate Font (DF) - deactivates one or more coded fonts.

$D65D

End (END) - represents the ending of some objects (image, graphics, bar code, downloaded font).

$D6BF

End Page (EP) - marks the end of a page, an overlay, or a page segment.

$D69F

Load Copy Control (LCC) - initializes the printer to a new sheet and defines the generation of the output from received page data.

  • Maximum of 128 copy groups
  • Maximum of 10 overlays per copy group
  • Maximum of 10 suppression IDs per copy group, suppression IDs $01 through $FF
  • Entry byte count values are $02 through $48

$D63F

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

  • Local font IDs:
    • $00 through $FE
    • $FF is invalid
  • Font inline sequence values:
    • $0000 and $5A00 are supported for resident fonts
  • 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:
Bit Value Definition
0 - 3 0 Ignored
4 0 - 1 Italicized Print
5 0 - 1 Bold
6 0 - 1 Double Strike
7 0 - 1 Double Wide
  • 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.

$D6CF

Logical Page Descriptor (LPD) - defines the characteristics of the current logical page for a sent page or overlay.

    • $1626 / 5670 L-units per 10 centimeters
  • Colors are identical to those in the Set Text Color (STC) text control of the Write Text (WT) command
  • If all ordered data flags are set, text will be directly passed to the printer; graphics, bar codes and images are always buffered. If one of the flags is reset, all data is buffered.
