The official 123.hp.com portal is HP’s recommended starting point for all new LaserJet printer setups. Follow these steps carefully:

1. Unbox your HP LaserJet and remove all packing tape and protective materials from the printer body, cartridge area, and paper tray.
2. Install the toner cartridge by opening the front or top door, removing the cartridge from its packaging, pulling the orange tab to remove the protective seal, and sliding it into the cartridge slot until it clicks.
3. Load plain white paper into the input tray and adjust the paper guides to fit snugly against the paper edges.
4. Connect the power cord and press the Power button. Wait for the printer to complete its startup process (the control panel lights will stabilize).
5. On your computer, open a web browser and navigate to 123.hp.com.
6. Enter your exact HP LaserJet model number (found on the front or bottom label of your printer) and click Begin.
7. Download the HP LaserJet driver and software package appropriate for your operating system (Windows or macOS).
8. Run the downloaded file and follow the HP Setup Wizard on screen. Choose USB or Wireless connection when prompted.
9. Print a test page when prompted to confirm the setup is complete.

Follow these steps to bring your HP LaserJet back online:

1. Click the Start menu and open Settings (gear icon).
2. Go to Bluetooth & devices (Windows 11) or Devices (Windows 10) and click Printers & scanners.
3. Click your HP LaserJet printer, then click Open print queue (or Manage then Open print queue).
4. In the print queue window, click the Printer menu at the top and make sure “Use Printer Offline” does NOT have a checkmark. If it does, click it to uncheck it.
5. Also check that “Pause Printing” is unchecked.
6. If jobs are stuck in the queue, select all and delete them. Then try printing a new test page.
7. If the problem continues, restart the Print Spooler service: Press Win + R, type services.msc, find Print Spooler, right-click, and click Restart.

A corrupt or outdated driver is the #1 cause of HP LaserJet setup failures. Here is how to cleanly reinstall your driver:

1. Go to Control Panel > Programs > Programs and Features and uninstall any existing HP printer software completely.
2. Restart your computer after uninstalling.
3. Open your browser and go to HP’s official driver page at support.hp.com/drivers.
4. Type your HP LaserJet model number into the search box and press Enter.
5. Select your operating system from the dropdown. HP will display the recommended driver package at the top.
6. Click Download next to the HP LaserJet Full Feature Software and Driver (preferred) or the basic driver if disk space is limited.
7. Once downloaded, right-click the installer file and select Run as administrator.
8. Follow the installation wizard. When asked for connection type, choose USB if using a cable, or Wireless / Network if connecting via Wi-Fi.
9. Complete the wizard and print a test page to verify.

HP LaserJet printers with wireless capability can connect to your home or office Wi-Fi network for easy printing from any device. Follow these steps:

Method A: Using the Printer’s Control Panel (Touchscreen Models)

1. On the printer’s front panel, tap the Wireless or Network icon (looks like radio waves).
2. Tap Wireless Setup Wizard and then tap Continue.
3. The printer will scan for available Wi-Fi networks. Select your network name (SSID) from the list.
4. Enter your Wi-Fi password using the on-screen keyboard. Passwords are case-sensitive — double-check carefully.
5. Tap OK or Done. The printer will connect and the wireless light will become solid (not blinking).

Method B: Using the HP Smart App (All Models)

1. Download the HP Smart app from the App Store or Google Play Store.
2. Open the app and tap the + icon to add a printer.
3. Follow the in-app setup wizard which walks you through connecting your printer to Wi-Fi step by step.
4. Confirm your Wi-Fi network and enter the password when prompted.
5. Once connected, the HP Smart app shows your printer as “Available.”

1. Check that your HP LaserJet is powered on, has paper loaded, and shows no error lights on the control panel.
2. Open the print queue: go to Settings > Printers & scanners, click your HP LaserJet, then Open print queue.
3. Select all stuck print jobs, right-click, and choose Cancel. Confirm cancellation.
4. Press the Win + R keys, type services.msc and press Enter.
5. Scroll down to find Print Spooler. Right-click it and select Stop.
6. Now open File Explorer and navigate to: C:\Windows\System32\spool\PRINTERS
7. Delete all files inside the PRINTERS folder (do NOT delete the folder itself, only its contents).
8. Return to Services, right-click Print Spooler, and click Start.
9. Try printing a test page. It should print immediately.

Blank or faded pages are almost always a toner cartridge issue. Follow these steps before replacing the cartridge — you may save money:

1. Open the printer’s front or top door to access the toner cartridge.
2. Grip the cartridge handle firmly and pull it straight out of the printer.
3. Hold the cartridge horizontally with both hands and gently rock it side to side 5–6 times to redistribute remaining toner evenly.
4. Slide the cartridge firmly back into its slot until it clicks into place. Close the door.
5. Try printing a test page. If print quality improves but is still faded, the toner is low and the cartridge needs replacement.
6. If pages are still completely blank, check that the orange protective seal was fully removed from the cartridge when you first installed it. A partially removed seal blocks toner flow.
7. For a confirmed empty or defective cartridge, order a genuine replacement from HP’s official toner store at hp.com. Genuine HP toner is engineered specifically for your printer model.
