As a proprietary internal tool, HP does not provide a direct download on its official drivers page .

The safest place to download HP software is directly from the official HP website. Navigate to the support section, and enter your device model to find the appropriate software.

Upload the file to (www.virustotal.com). If more than 3 engines flag it as malware, do not use it.

You generally should not try to download Hpbq138.exe directly from a third-party website. "EXE download" sites often bundle malware with legitimate filenames.

This guide is for informational purposes only. The filename Hpbq138.exe is not a standard, publicly documented HP filename. It is highly likely to be either an outdated legacy file, a misnamed driver component, or (more probably) malware disguised as an HP tool. Proceed with extreme caution.
