Quick answer HP makes several apps and diagnostic tools to help you set up, troubleshoot, and maintain your printer. This guide explains what each one does and which tool fits your situation—whether you need to fix a scanning issue, diagnose a problem, or just get started.

When your HP printer stops working or won't cooperate, you have options. HP includes multiple built-in apps and free diagnostic tools designed to handle different problems.

This hub organizes the most useful HP applications and explains what each one actually does—no marketing jargon, just practical details. Whether you're setting up a new printer, troubleshooting a specific error, or running a full diagnostic, you'll find the right tool and clear instructions here.

Where to start

Start Here: Diagnostic and Repair Tools

If something's wrong with your printer, start with diagnosis before you panic. The HP Print and Scan Doctor: Download, Run, and Interpret the Results is the most direct tool—it's a small program that finds and fixes common scanning and printing problems automatically. Run this first if printing or scanning fails.

For a broader view of your printer's health, HP Diagnostic Tools: A Decision Tree for Printer Problems walks you through different failure types and points you toward the right fix. This helps when you're not sure what's actually broken.

Setup and Installation Tools

New printer sitting in a box? HP Easy Start Setup Guide for Printer Installation handles driver installation and network setup in one go. It's built to make first-time setup faster and catch common mistakes.

HP Support Assistant: What It Does and When to Use It monitors your printer in the background after setup is complete. It alerts you to driver updates, checks for known issues, and can run quick health checks without user action.

Daily Use and Scanning Apps

HP Smart App Guide: Setup, Scan, Print, and Troubleshooting is the modern mobile-first choice. Use it to print and scan from your phone or tablet, manage print jobs, and get ink level alerts. It's easier than older desktop tools for casual users.

HP Printer Assistant: Features, Shortcuts, and Common Fixes is the desktop alternative when you need more control. This tool handles batch scanning, custom shortcuts, and lets you tweak print settings directly from your computer.

Mac Users and Supply Management

HP Utility on Mac: Printer Maintenance and Supply Tools is built specifically for macOS. If you're on a Mac, use this to check ink levels, order supplies, run maintenance cycles, and diagnose issues without hunting for third-party software.

Windows Legacy and Modern Alternatives

HP Solution Center Alternatives for Modern Windows explains what happened to HP Solution Center and what to use instead on Windows 10 and 11. Older guides may tell you to use Solution Center—it's outdated. This guide points you to current tools instead.

Which Tool Should You Pick?

For a broken printer: Start with HP Print and Scan Doctor. It solves most common print and scan failures without you doing anything complicated.

For setup: Run HP Easy Start, then let HP Support Assistant keep watch.

Frequently asked questions

What's the difference between HP Print and Scan Doctor and HP Support Assistant?

HP Print and Scan Doctor fixes specific print and scan failures right now—it's a one-time diagnostic and repair tool. HP Support Assistant runs in the background after setup, monitors your printer's health, and alerts you to updates and known issues. Use Doctor to fix a problem; use Assistant to prevent problems.

Can I use HP Smart App instead of HP Printer Assistant?

Yes, for most users. HP Smart App handles printing and basic scanning from phones and computers. HP Printer Assistant gives you more control over batch scanning, custom shortcuts, and advanced print settings. Pick Smart App for simplicity, Printer Assistant for power users.

Do I need all these tools installed at once?

No. Install HP Easy Start during setup, let Support Assistant run in the background for monitoring, and add HP Smart App or Printer Assistant based on how you use your printer. You don't need every tool active—keep it simple.
