I don't work for TP-Link, but I did look at your router manual, https://static.tp-link.com/2020/202001/20200119/1910012697_Archer%20AX6000%201.0_UG_REV1.1.0.pdf.
From it, Chapter 7:
=======================
This chapter describes how to use the USB ports to share files and media from the USB storage devices over your home network locally, or remotely through the internet.The router supports USB external flash drives and hard drives.It contains the following sections:
=======================
Many routers no longer ship with Print Servers as so many printers these days are also wireless.
My Archer A20 V1 only supports hard drive and Time Machine on the USB port. Even my older Netgear only did these.
I might be wrong though, if so, someone will correct me.
