How to read the meter reading of printer?
WMI- Verified every property of it still no answer. must be something else..
Manufacturer - Doesn't provide solution since they own different tools/ products for this. but I think this must be a simple for a programmer to find it out..
Anything in
System.Drawing.Printing? (winforms/Console)
System.Printing ? (WPF)
preferably - FujiXerox and KonicaMinolta
[UPDATE] I have seen an example of SNMP communication with printer using OLEPRNLib ,sample code is given below
string[] ErrorMessageText = new string[8];
ErrorMessageText[0] = "service requested";
ErrorMessageText[1] = "offline";
ErrorMessageText[2] = "paper jammed";
ErrorMessageText[3] = "door open";
ErrorMessageText[4] = "no toner";
ErrorMessageText[5] = "toner low";
ErrorMessageText[6] = "out of paper";
ErrorMessageText[7] = "low paper";
int DeviceID = 1;
int Retries = 1;
int TimeoutInMS = 2000;
string CommunityString = "public";
string IPAddressOfPrinter = "192.168.1.110";
// Create instance of COM object
OLEPRNLib.SNMP snmp = new OLEPRNLib.SNMP();
// Open the SNMP connect to the printer
snmp.Open(IPAddressOfPrinter, CommunityString, Retries, TimeoutInMS);
// The actual Warning/Error bits
uint WarningErrorBits = snmp.GetAsByte(String.Format("25.3.5.1.2.{0}", DeviceID));
// The actual Status
uint StatusResult = snmp.GetAsByte(String.Format("25.3.2.1.5.{0}", DeviceID));
// uint Result2 = snmp.GetAsByte(String.Format("25.3.5.1.1.{0}", DeviceID));
string Result1Str = "";
switch (StatusResult)
{
case 2: Result1Str = "OK";
break;
case 3: Result1Str = "Warning: ";
break;
case 4: Result1Str = "Being Tested: ";
break;
case 5: Result1Str = "Unavailable for any use: ";
break;
default: Result1Str = "Unknown Status Code : " + StatusResult;
break;
}
string Str = "";
if ((StatusResult == 3 || StatusResult == 5))
{
int Mask = 1;
int NumMsg = 0;
for (int i = 0; i < 8; i++)
{
if ((WarningErrorBits & Mask) == Mask)
{
if (Str.Length > 0)
Str += ", ";
Str += ErrorMessageText[i];
NumMsg = NumMsg + 1;
}
Mask = Mask * 2;
}
}
Console.WriteLine(Result1Str + Str);
The above is working and able to get a bit of printer information, so I am hoping to get Meter reading passing correct OID.
To find out the OID , I used iReasoning MIB Browser.. but could not get what I want here.. any thoughts?
