Routine Description:
This routine determines whether or not the driver can print the job
described by pDevMode on the printer described by hPrinter. 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.

DevQueryPrintEx(
PDEVQUERYPRINT_INFO pDQPInfo
)
/*++
Routine Description:
This routine determines whether or not the driver can print the job
described by pDevMode on the printer described by hPrinter
Arguments:
pDQPInfo - Pointer to DEVQUERYPRINT_INFO data structure
typedef struct _DEVQUERYPRINT_INFO {
WORD cbSize; // size of this structure in bytes
WORD Level; // Level of this info, 1 for this version
HANDLE hPrinter; // handle to the printer for the query
DEVMODE *pDevMode; // pointer to the DEVMODE for this job.
LPTSTR pszErrorStr; // pointer to the error string buffer.
WORD cchErrorStr; // count characters of pszErrorStr passed.
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.
