Printer

[Stanley]

Hi all! I have a printer attached to my PC, and I share it to my LAN.
The problem is how can I know which computer print the document, and
how many pages they printed by using VB .Net! Thanks!

Sime pointers:

WMI + 'Win32_PrintJob' (properties 'HostPrintQueue', 'Owner').

I still have some problem please help me! The problem is that when I
try to do WQL
"SELECT * FROM Win32_PrintJob" in a do-loop thread, it eat nearly 10%
of my CPU! So is there away to do the WQL statement when needed? Ex:
only when printer has activity! Thanks

Stanley,

Mostly is it sufficient to set a sleep in the loop.
threading.thread.sleep(1000), which means 1 second.

I hope this helps.
