i'm trying to get information of a printer. Using WMI i can retrieve some information but only if a job has been sent.
I need to check if my printer is out of paper before sending a job.
Is this possible?

I haven't used it myself but have a look here:
http://msdn.microsoft.com/en-us/library/system.printing.printqueue.isoutofpaper.aspx
This is how i did it...
//check PAPER OK and Toner OK
private static bool IspaperOK(ManagementBaseObject printer)
{
bool PaperOK = true;
string[] printers = ConfigurationManager.AppSettings["ModelliStampanti"].Trim().Split('#');
foreach (var property in printer.Properties)
{
if (property.Name == "DeviceID")
{
var PaperStatus = printer.Properties["PrinterState"].Value.ToString();
for (int i = 0; i <= printers.Length - 1; i++)
{
if (property.Value.ToString() == printers[i].ToString())
{ //131072 = Toner Low
//1024 = printing
//16 = Out of Paper
//5 = out of paper
//128 - offline(no internet connection)
//this is for out of paper....
if ((PaperStatus == "5") ||(PaperStatus == "16"))
{
PaperOK = false;
}
//this is for low toner....
if (PaperStatus == "131072")
{
PaperOK = false;
}
}
}
}
}
return PaperOK;
}
To verify these problems use these values instead of values described in MSDN
//131072 = Toner Low
//1024 = printing
//16 = Out of Paper
//5 = out of paper
//128 - offline(no internet connection OR printer turned off )
