Hi, I am trying to read the status of a printer session in order to automate downloading reports using Excel VBA.
I have been so far unsuccessful in retrieving the OIA (operator information) area or presentation space of a print session with OLE and ehlapi32.dll API to inquire if the session is "idle" (Finished downloading a report).
I want to capture the "Device busy" bit in Byte 90 of the OIA string so I my program will know when the printer session is not busy so I can send the next print job to the printer session.
Ideally, I would also like to capture the page count in a variable that is displayed in the printer session window as well to kept track of the number of pages printed.
My printer session connects via a SNA connection using LU3.
Any help would be greatly appreciated.
