For many users, the SLP‑T80W is a plug‑and‑play printer. When you connect the printer to your PC with a USB cable, Windows will automatically detect it and attempt to install a basic, compatible driver. In some cases, no manual download is required at all. According to user feedback and retail Q&A pages, the printer works out of the box with Windows 10 and 11 without needing additional drivers.

Run the interface cable (USB or Ethernet LAN) from the back panel directly to your PC or network router. Phase B: Software Installation

If the printer does not appear automatically, Windows Update can often fetch the correct driver from Microsoft’s servers.

Once you have obtained the driver package (either as an .exe installer or as a set of .inf files), follow these instructions carefully.
