You can use the GXJobFormatModeQuery function to get or set additional information related to a job format mode.

void GXJobFormatModeQuery (gxJob aJob, gxQueryType aQueryType,
                           void *srcData, void *dstData);

aJob

A reference to the job object for which information relating to the printer's format mode is being requested.

DESCRIPTION

The GXJobFormatModeQuery function obtains information from a printer driver that relates to the printer driver's preferred mode. The kinds of queries that can be specified in the aQueryType parameter depend on the printer driver. The format and direction of the data transfer depends on the kind of query.

QuickDraw GX defines query types for use with printer drivers whose preferred mode is gxTextJobFormatMode:

Constant	Value	Explanation
gxGetJobFormatLineConstraintQuery	0	Used to determine line constraint characteristics
gxGetJobFormatFontsQuery	1	Used to determine font information
gxGetJobFormatFontCommonStylesQuery	2	Used to determine style names
gxGetJobFormatFontConstraintQuery	3	Used to determine font positioning constraints
gxSetStyleJobFormatCommonStyleQuery	4	Used to set style names
