Hey Vipin,
Great to find you!
I dont believe you still lurk around these groups!
Starting and stopping spooler does not help. I tried doing..
pPrinterInfo5->Attributes |= PRINTER_ATTRIBUTE_WORK_OFFLINE;
SetPrinter (hPrinter, 5, (LPBYTE)pPrinterInfo5, 0);
It caused the printer icon to be grayed. But whenever I
connect/disconnect the USB cable of the printer, the status
automatically changes to 'ready' and icon becomes un-grayed. Something
in windows (usbmon?) is setting the status to online.
This behavior is consistent with when i manually do a 'Use Printer
Offline' and then connect/disconnect the cable.
Hope to bump into you again!

Hi Namit,
Interesting. Does it appear grayed if you stop and start the
spooler?

Hi,
I wish to set the status of a printer to offline. I was able to do it
using SetPrinter() API (code below). But the icon of the printer in
'Printers and Faxes' folder remains the same. How can I make the icon
gray (dim) programmatically?
Note that when you select 'Use Printer Offline' manually, the icon
becomes gray automatically.
TIA.
Code to set status of printer to offline. I verified that the printer
is actually offline by printing a job. The job was not spooled which
confirmed that the spooler is aware that the printer is offline.

HANDLE hPrinter = NULL;
PRINTER_DEFAULTS pd;
pd.pDatatype = NULL;
pd.pDevMode = NULL;
pd.DesiredAccess = PRINTER_ACCESS_ADMINISTER;
BOOL bOpen = OpenPrinter(L"HP LaserJet 3050 Series PCL 5e", &hPrinter,
&pd);
PRINTER_INFO_6 pi6;
pi6.dwStatus = PRINTER_STATUS_OFFLINE;
BOOL bSet = SetPrinter(hPrinter, 6, (LPBYTE)&pi6, 0);
