If if can, it puts zero into pdwErrIDS. If it cannot, it puts the resource id of the string describing why it could not. Arguments: hPrinter - Handle to the printer to be checked pDM - Point to the DEVMODE passed in pdwErrIDS - Point the the DWORD to received resource string ID number for the error. Return Value: This routine returns TRUE for success, FALSE for failure. when it return TRUE, the *pdwErrIDS determine if it can print or not, if *pdwErrIDS == 0, then it can print else it contains the string ID for the reason why it can not print.

WORD cchNeeded; // count characters of pszErrorStr needed. } DEVQUERYPRINT_INFO, *PDEVQUERYPRINT_INFO; cbSize - size of this structure Level - This must be one (1) for this version of structure hPrinter - Identifies the printer on which the job is to be printed. pDevMode - Points to the DEVMODE structure that describes the print job that is to be determined as printable or non-printable by hPrinter. The driver should always validate the DEVMODE structure whenever it is passed in. pszErrorStr - This is the pointer to a null terminated unicode string which to stored the reason for non-printable job. If the job is printable then it return TRUE. If the job is non-printable then it return FALSE, and a null terminated unicode string pointed by the pszErrorStr for the reason by this job is not printable. The size of this buffer in characters is specified by the cchErrorStr. cchErrorStr - Specified the size of pszErrorStr in characters (includs null terminator) when calling this function. If an error string is returned due to the non-printable job (returned FALSE), the driver will set ccchNeeded to the total characters (includes null terminator) required for the pszErrorStr, in this case the driver must always truncate the error string to fit into the pwErrorStr (only if it is not NULL) passed up to the cchErrorStr characters passed. cchNeeded - When driver returned FALSE, it specified total characters required for the pszErrorStr. If cchNeeded returned from the driver is larger then the cchErrorStr then it indicate the passed pszErrorStr is too small to hold the full error string, in this case the driver must always truncate the error string to fit into the pszErrorStr passed up to the cchErrorStr size. Return Value: BOOLEAN - TRUE - The job is printable and should not be hold. FALSE - The job is not printable and cchNeeded in the DEVQUERYPRINT_INFO data structure specified total characters required for the pszErrorStr. If returned cchNeeded is greater then cchErrorStr passed then it indicated that pszErrorStr is too small for storing the error string, in this case the driver must always truncate the error string to fit into the pszErrorStr passed, up to the cchErrorStr characters. *Note* The driver should have some predefined generic resource error strings for some possible known errors. such as memroy allocation error, data file not found, invalid devmode,... for returning non devmode related errors. The caller can pre-allocated larger buffer (such as 256 wchars) for storing the error string rather than calling this function twice.
