Win API spooler functions usage

[hiptino]

I'm currently writing a Printer Monitor software with VB6.<br>I employed two Win API spooler functions, Enumjobs() and GetPrinter().<br>These two functions returns a status member which can be used to determine the status of a printjob and the printer.<br><br>I tested the software, the JOB_INFO_2 status memmber was able to detect the status of the printjob when it's printing,spooling or paused. Also the PRINTER_INFO_2 status member was able to get the status of the printer when it is paused. But the PRINTER_INFO_2 status member could not determine the status of the printer when there is a paperjam, paperout,printing and other possible status, when I intentionally create those(paperout,paperjam..)situations. Likewise if there is a successful printing, the JOB_INFO_2 status member does not indicate "JOB_STATUS_PRINTED".<br><br>I could not find a clue as to the cause of this problem.<br>I used printers HP1120C, HP895cxi, OKIPAGE3+ and Win98, WinNT 4.0 for the test.<br>Could it be that the Enumjobs() and Getprinter() APIs are obsolete.<br>Or could it be that the these constants<br>(Public Const PRINTER_STATUS_PAPER_JAM = &H8)<br>(Public Const PRINTER_STATUS_PAPER_OUT = &H10)..etc<br>are no longer supported.<br><br>Please, I would appreciate any suggestion you have. This particular problem has been delaying my project.<br><br>Thank you,
