Here’s a step-by-step guide to downgrade the firmware on an HP OfficeJet Pro 6950 printer.

What You Will Need:

  • HP OfficeJet Pro 6950 printer fully powered on
  • Windows PC (recommended; Mac is more difficult)
  • USB A/B printer cable (do not rely on Wi-Fi for downgrade)
  • Old firmware file (look for version LBP1CN1812AR or LBP1CN1745BR – these are pre-dynamic security)
  • HP Firmware Update Utility (included in the firmware package)

What is Firmware, and Why Does HP Update It?

Firmware is the low-level software embedded inside your printer’s hardware. It controls everything from printing speed to how the printer communicates with ink cartridges.

HP periodically releases firmware updates for the 6950 series. Officially, these updates are meant to:

  • Fix bugs and connectivity issues (Wi-Fi, USB)
  • Improve print quality
  • Add security patches

However, many users believe that some updates intentionally disable the printer’s ability to use non-HP or remanufactured ink cartridges. This is often referred to as “dynamic security.” HP has confirmed that some updates are designed to block cartridges that use non-HP chips, even if they worked perfectly before.

Method B – Using a .BDL file (Remote Firmware Update)

If you only have a .bdl file:

  1. Open your browser.
  2. Go to the printer’s IP address (find it via Network menu on printer).
  3. Log in as admin (default password is often the printer’s PIN or serial – check sticker).
  4. Navigate to Tools → Firmware Update → Select File.
  5. Choose the older .bdl file.
  6. Click Update.

1. Prepare the Printer

  • Turn on the printer.
  • On the control panel, go to Setup → Network → Network Status → Disable Wi-Fi (or simply unplug Ethernet).
  • Factory reset (optional but helps):
    Setup → Printer Maintenance → Restore → Restore Factory Defaults.

Step 1: Find a Compatible Older Firmware

HP does not officially host old firmware versions. You can try:

  1. Third-party sites (e.g., “HP OfficeJet Pro 6950 firmware archive” – search carefully).
  2. Old driver packs from HP’s FTP (if still accessible).
  3. Backup copies you or someone else saved before updating.

Firmware example: OJ6950_xxx.bdl or HP_OJ6950_xxxx.exe
