Board index FiveWin for Harbour/xHarbour Check if a device was connected
Was connected or still is connected ?
Both works for me.
But know if the device still is connected will provide me a better solution

Samir,
I'm not sure what you are looking for, but the function below will tell you if a specified printer is setup on that PC.
FW's own function getPrnName() returns the name of the current printer.

function isPrinterModel( cModel )
local aPrinters:= getPrinters(), i:=0, lSuccess:=.f.
for i = 1 to len( aPrinters )
if aPrinters[i] = cModel
lSuccess:=.t.
endif
next
return lSuccessFWH 18.05/xHarbour 1.2.3/BCC7/Windows 10
James, the printer isn't recognized as a printer by the OS.
Here in Brazil we have the ECF ( Emissor de Cupom Fiscal ) something like fiscal coupons emitter, thermal printers with a specific firmware that must be used to print valid coupons to collect taxes.
Most of them connect through the serial port, some connect via USB, but create a virtual serial port and a specific brand connects via USB, but creates another type of device (USBIO).
I need to know if this device is connected.

Samir,
OK. Well I don't know the answer to that one.
Here is a manual for setting up USB drivers which may help. Perhaps you can find a registry entry that you could search for.

And here is a little utility program that will list all the USB devices that have ever been connected. It doesn't solve your problem but maybe it will be useful in finding a solution.
