Constants and Data Types for Advanced Printing Features

Job Format Modes

QuickDraw GX provides job format modes that allow a printer driver and an application to negotiate the best mode for printing. The gxJobFormatMode data type specifies modes, which are enumerated as follows:

enum {
   /* direct modes for job objects */
   gxGraphicsJobFormatMode    = (gxJobFormatMode) 'grph',
   gxTextJobFormatMode        = (gxJobFormatMode) 'text',
   gxPostscriptJobFormatMode  = (gxJobFormatMode) 'post'
};
typedef OSType gxJobFormatMode;

Constant descriptions

gxGraphicsJobFormatMode

If set, QuickDraw GX uses graphics mode.

gxTextJobFormatMode

If set, QuickDraw GX uses text mode.

gxPostScriptJobFormatMode

If set, QuickDraw GX uses PostScript mode.

The application calls the GXSetAvailableJobFormatModes function to inform the printer driver of the modes that the application supports, using a gxJobFormatModeTable structure to identify the supported modes.

struct gxJobFormatModeTable{
   long              numModes;      /* number of direct modes */
   gxJobFormatMode   modes[1];      /* any number direct modes */
};

Field Description

numModes

The number of modes that the application supports.

modes[1]

An array that contains the modes.
