GetPrinterInfo
This function is used to obtain information about printers, such as the name of the printer or whether the printer can print in color.
Syntax
DWORD WINAPI GetPrinterInfo( HANDLE hPrint, DWORD dwOption, PVOID pBuff, PDWORD pBuffLen );
Parameters
- [IN] hPrint
- Handle obtained from the PrinterOpen function.
- [IN] dwOption
- Specifies the printer option to retrieve. The following options are available in Windows CE 2.10 and later:
- PRINTER_ID
- Retrieves the name of the printer. The parameter pBuff must point to a string previously allocated by the calling application. If pBuff is NULL, this function returns ERROR_SUCCESS, and pBuffLen contains the number of characters needed to store the printer name, including the terminating null character. If pBuffLen is NULL, this function returns ERROR_INVALID_PARAMETER. If pBuffLen is not long enough to hold the name of the printer, this function returns ERROR_MORE_DATA along with the correct number of characters needed, including the terminating null character in pBuffLen.
- PRINTER_PEN

- [OUT] pBuff
- If pBuff is NULL, this function returns the size of the requested information in the pBufLen parameter, including any terminating null characters. If pBuff is not NULL, this function returns the requested information in the location pointed to by pBuff.
- [IN/OUT] pBuffLen
- On output, pBufLen contains the size of the requested data. If pBufLen is NULL, this function returns ERROR_INVALID_PARAMETER.
