 1. What causes this error?

This error occurs when you are trying to install a driver designed for a standard 64-bit (x64) Windows system on a computer that uses an ARM-based processor (e.g., devices with Snapdragon chips).
  • Reason: ARM processors require a specific, ARM-compatible version of the driver software. The standard x64 driver installer (DPInst.exe) will not work.

2. How to Fix the Error

Follow the steps below to download and install the correct driver for your ARM-based computer.
Step 1: Download the ARM-Compatible Driver

Step 2: Install the Driver and Add Your Printer
  1. Locate the downloaded file on your computer (usually in your Downloadsfolder).
  2. Double-click the file to run the installer.
  3. Follow the on-screen instructions provided by the installer to add printer the setup.

3. What if my web browser deletes the driver file?

Some browsers (like Chrome or Edge) may flag the driver file and automatically delete it for security reasons.
  • Solution: If this happens, you will need to explicitly allow the file. When you see a warning message at the bottom of your browser, look for an option like "Keep" or "Show more" > "Keep anyway".
  • Reference: Please refer to the provided screenshot for a visual guide on how to trust and keep the installation package in your specific browser.
