How to check Printer is connected or not to your PC by Java?

Question

I am able to get the name of printer which I had installed previously on my PC.But now its not physically connected to my pc. How should I check it first before moving to Print(

Answer 1

Another way is to use PowerShell and query:

Get-WmiObject -Query "Select * From Win32_PnPEntity where deviceid like 'USBPRINT\\%' and caption like '%Canon%'"

This way, you get result only if printer is connected.

You can query WMI from Java with many libraries, search "WMI Java library".
