Inside Macintosh: QuickDraw GX Printing Extensions and Drivers /

Chapter 3 - Printer Drivers / User Interface and Chooser Support

Providing Printing Choices

You can use the dialog panel ('ppnl') resources to provide QuickDraw GX with information to be displayed in dialog panels.

• The dialog panel resource gives QuickDraw GX the information necessary to display a panel.
• The extended dialog panel resource (resource type 'xdtl') provides QuickDraw GX with the information it needs to execute panel controls.

These resources are described in Inside Macintosh: QuickDraw GX Printing.

You can also modify the choices that are displayed to the user in the print dialog boxes by changing the values in the job collection. You can access and modify these values by using the appropriate tags (as described in the section "Using the Printing-Related Collections" beginning on page 3-20). Among the items that you might need to modify are the following:

• paper-tray availability
• print-quality choices
• print-scaling boundaries
• printing-file options
