Great question! Most printers typically have an app that to download, others just require you to share the wireless network! Do you have your user manual for the printer in question? It should help give you some direction!
As a heads up, I went ahead and marked this as a question rather than a discussion, this will give more visibility and make it more likely for others to chime in!
I'm also going to be sending you a PM real quick, if you can check your inbox here https://support.t-mobile.com/inbox I'd appreciate it!
Hi hi! Just wanted to check in and see if you'd been able to find and download a print-to app for your printer. As Lauren mentioned, many recent printers simply require connecting the device to the same Wi-Fi network, but you might need to set the permission up first. Let us know if you're still looking for help with this!
