Ssdal Get Status S’abonner

I run this command to get the status of a printer in a command window, but if the printer is open or even if the printer is off it ALWAYS have a "ready" status. What am I doing wrong?

C:\windows\ssdal.exe /p "TSC TDP-245" get status

or

C:\windows\ssdal.exe /a get status

Everything says ready but its not.
