Printer drivers must process requests from applications for new DeviceCapabilities indexes. A driver's DeviceCapabilities function must check for and process the following values.
| Value | Meaning |
| DC_ENUMRESOLUTIONS (13) | Retrieves a list of resolutions supported by the printer model. |
| DC_FILEDEPENDENCIES (14) | Retrieves a list of filenames which also need to be installed when the driver is installed. |
| DC_TRUETYPE (15) | Retrieves the driver's capabilities with regard to printing TrueType fonts. |
| DC_PAPERNAMES (16) | Enumerates the actual string describing the names of the papers. |
| DC_ORIENTATION (17) | Retrieves the relationship between Portrait and Landscape orientations in terms of the number of degrees that portrait orientation is to be rotated counterclockwise to achieve landscape orientation. |
| DC_COPIES (18) | Retrieves the maximum number of copies the device can print. |
The implementation of one or all of the indexes is optional. If a driver does not implement a given index, the DeviceCapabilities function should return -1. For more information about the new indexes, see the DeviceCapabilities function in the Microsoft Windows Device Driver Adaptation Guide.
