i have tried the code but there is another problem.
pJob parameter of EnumJobs returns informations of the buffer.
can you tell me the structure of the parameter ?
because this contains the jobid that i need for GetJob function.

Declare Integer EnumJobs in WinSpool.Drv as WS_EnumJobs ;
Integer hPrinter, ;
Integer FirstJob, ;
Integer NoJobs, ;
Integer Level, ;
String @pJob, ;
Integer cbBuf, ;
Integer @pcbNeeded, ;
Integer @pcReturned
