问题
I want to monitor the system scope's printing jobs through a standalone program using the Windows Spooler API, but only the print job's name can be fetched. How do I get the original file with full path.
回答1:
If you are looking for the original document path (e.g. location of Word Document that you just printed), the spooler will not be able to tell you this.
The spooler generally receives files through the GDI or XPS paths. The application that does the printing effectively sends the spooler a series of graphical commands (via the appropriate device driver) which the spooler service will cache into a temporary file before sending to the printer. This means the spooler itself does not know anything about the originating source file, or where it is located.
If you are wondering how the spooler gets the document name, it is done via the StartDoc call that will pass in a DOC_INFO_x structure. That is about all the information that the spooler receives with regard to the source document itself.
