Nothing easier on windows: there's a very useful library called OLEPRN.DLL sitting in system folder.
You may use VBS like follows:
dim o
' create an COM object to communicate to network printer
set o = createobject("oleprn.olesnmp")
' open a snmp session to printer using its IP address, public interface, retry count 1 and 6000 msecs as timeout
o.open "192.168.1.18","public",1,6000
' get printer state by state OID
x = o.GetAsByte("25.3.2.1.5.1") '
' output the state: 2 is OK, all others are warning/error codes '
' change MsgBox to desired notification method '
MsgBox x
You may want to write a C++ code:
#include
"stdafx.h"
#import
"d:\\windows\\system32\\oleprn.dll" no_namespace
#define USAGE _T("usage: %s <printer IP address>\nsample: %s 10.10.10.10")
int _tmain(int argc, _TCHAR* argv[])
{
if(argc < 2)
{
wprintf(USAGE,argv[0],argv[0]);
return -1;
}
CoInitialize(NULL);
ISNMPPtr aPtr;
_bstr_t bstrHost(argv[1]);
_bstr_t bstrCommunity("public");
_bstr_t bstrOID("25.3.2.1.5.1");
HRESULT hr = S_OK;
try
{
hr = aPtr.CreateInstance(__uuidof(SNMP));
hr = aPtr->Open(bstrHost,bstrCommunity);
int iStatus = aPtr->GetAsByte(bstrOID);
printf("Status %d\n",iStatus);
aPtr.Release();
}
catch(_com_error *e)
{
wprintf(e->ErrorMessage());
}
catch(...)
{
wprintf(_T("Unknown error occured\n"));
}
CoUninitialize();
return 0;
}
Or you may want to get it working in managed code:
