Identical printers can be confusing but there few things you can do to be able to identify which one to print on.
- You can give you printer name to identify it
- Switch off one of the printers from the power when you select to print it will show you the printer that is ready for you to send your work to it.
- The other offline one would not print as it would help you to identify the one that is ready from the computer or your smart phone.
- You can also decide to connect one printer wireless and other hard wired using USB cable. In this case before you print with USB cable you need to connect the cable to your PC to be able to print. I hope this help you it is a question I was asked recently.
