To obtain the official HP printer support phone number for technical assistance, start by visiting the official HP website. Here, you'll find a dedicated page for printers. Select your specific printer model and locate the support options. The official support phone number will be prominently displayed. Additionally, it's advisable to verify the number directly from the official HP website to ensure authenticity and avoid potential scams.
