// Printer-Escape Functions
//
// The printer-escape functions support device-specific operations. The
// following briefly describes these escape functions.
//
// ABORTDOC          The ABORTDOC escape function signals the abnormal
//                   cancellation of a print job.
//
// BANDINFO          The BANDINFO escape function RETURNs information about a
//                   band of bitmap data.
//
// ENDDOC            The ENDDOC escape function signals the end of a print job.
//
// NEXTBAND          The NEXTBAND escape function prints a band of bitmap data.
//
// QUERYESCSUPPORT   The QUERYESCSUPPORT escape function specifies whether the
//                   driver supports a specified escape.
//
// SETABORTDOC       The SETABORTDOC escape function calls an application's
//                   cancellation procedure.
//
// STARTDOC          The STARTDOC escape function signals the beginning of a
//                   print job.
//
// The previous list of printer escapes is a list of escapes supported by the
// Microsoft Windows Universal Printer Driver (UNIDRV.DLL). It is not a
// comprehensive list of all Windows escape functions. Most of the escape
// functions now have equivalent Windows API functions with Windows 3.1. The
// escapes are supported for backward compatibility, but application
// developers are encouraged to start using the new API calls.
