The normal procedure is to see if the cable is plugged in.

Look in the printers and faxes folder and then print a test page.

I "m trying to send a command to the printer from UI. If the printer
is not connected to the system,the UI hangs.So, I need to check
whether printer is available to send the command.If printer is not
available, I will display messagebox "No printer connected"
So , I need to check wheteher printer is available( connected to the
system or not?)

My Os is Win XP and I m developing the GUI in VC++. Ihave checked
PRINTER_INFO_6 in MSDN which gives the status of the printer in
printers and faxes folder.But I need to know whether the printer is
connected to the PC's parallel/serial port.

Hi
I m sending the command thru port monitor writeport,this writeport
takes time to recogonize that printer is not connected.
To send the first command printer should be there?
