To find an HP printer service center, you can follow these steps:

1. **HP Official Support**: Visit the [Official HP Printer Support](https://support.hp.com/us-en/printer) website for troubleshooting guides, warranty checks, and diagnostic tools. This might help you identify if your issue can be resolved without visiting a service center.

2. **Contact HP Customer Service**: Reach out to HP Customer Service via phone to inquire about authorized repair locations:
– For **Business Customers**: Call 866-625-0242 (Monday to Friday, 8 am – 8:30 pm EST) [2].
– For **Home Customers**: Call 888-999-4747 (Monday to Sunday, 9 am – 12 am EST) [2].

3. **Thumbtack for Local Repair Services**: Use platforms like [Thumbtack](https://www.thumbtack.com/k/hp-repair/near-me) to find local, community-rated repair services that might handle HP printers.

4. **Check Local Listings**: You can also search online for authorized HP service centers in your area using search engines. In Southern New Jersey, for example, you might find local repair shops by inquiring in HP forums or through local business listings.

If you are unable to find an authorized service center, contacting HP directly for assistance would be the best option.
