Is PrintSystemJobInfo.JobStream broken?

Question

I get a queue from the target printer and look through the list of jobs on it. When the job is not IsSpooling, I try to read JobStream to see the print job.

So far, JobStream has always been zero. My printed matter comes from a DOS application and should be clear text. I paused the printer to protect the rainforest, but I can still get buffered data, right?

Am I missing something or typing PrintSystemJobInfo.JobStream?

This value will almost always be zero. See this forum: http://www.vbforums.com/showthread.php?t=549634

If you want the actual binary JobStream to be the best, you need to read the spool file (.SPL) from the directory "C: \ Windows \ System32 \ spool \ PRINTERS". You can pause the job before printing it, or set the “save print jobs” setting as indicated in the message from the related forum. However, it should be remembered that this data comes in a gamut of formats, depending on the driver that creates the spool file and the application that initiates printing. Retrieving data from this stream is not a trivial task, as it will change from the printer driver to the printer driver. If you work with one single known printer, you may have success.
