L_LTPRINTER_API L_INT L_PrnGetRemoteData(pszPrinterName, nJobId, pJobData)
Obtains the remote data attached to the print Job ID.
Character string that contains the printer's name.
ID of the job to retrieve remote data.
Pointer to a PRNJOBDATA structure to be updated with the remote data.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
The L_PrnGetRemoteData function will obtain the pJobData structure data that was sent from the client machine printer driver, after the callback function L_PrnClntPrintJob was faired at the job is being printed.
