XpQueryScreens - Queries an X Server to determine which screens, of all the screens on the server, support the X Print Service Extension

Screen **XpQueryScreens ( display,
This request returns a non-NULL pointer to a list of screen pointers if one or more screens support the X Print Service Extension; otherwise it returns NULL.
XpQueryScreens determines if the X Print Service Extension is present, and if so, which of all the screens on the X Server support the X Print Service Extension. Unlike many other extensions, the X Print Service Extension may be restricted to a subset of all available screens - for example, a single X Server may be supporting video displays on some screens and printers on others.
The list of screen pointers can be freed by calling XFree.
