I have a HpDeskJet 3752 that refuses to work. I have tried to call the support line and use the virtual assitant because it says my serial number doesn't exist. The number is clearly printed and I have triple checked that I am submitting it correctly.

Welcome to the HP Community --
It is likely that the product Warranty is expired.
This would mean that the serial number cannot be used to submit an in-Warranty repair to HP Support.
Category Warranty & Repair
What?
HP Support – Hardware / Technical Support for Devices in Warranty
Registered Devices in Warranty:
Contact HP Support
Start here:
HP Support virtual repair center
Printers
Contact HP Support – Printer Support

Select your region and follow the prompts

---------------------------------------------------
Reminders - READ
Case submission to HP Support is available to those whose devices registered and are still in Warranty.
Some regions display phone / chat contact information only after the case is submitted online
Not every issue is covered under the standard Hardware Warranty. Purchased Care Pack Warranties differ by contract.
HP is not a "general" repair facility: Requests for out-of-warranty repairs are usually not accepted.
If the problem is hardware, if your device is in Warranty, if your device is Registered, and you cannot submit your case to Support, let us know and we will forward a request.
Important
HP Phone numbers you find on the Internet have likely been hijacked. Old HP phone numbers – those numbers no longer used by HP since the move to “online” case submissions – might have been taken over by thieves.
Do not be a victim.
Stay vigilant.

Out of Warranty? What to do...
For those of us who are "Out of Warranty", submitting a case to HP Support is not an option.
Open your device HP Product Home > Select Category Troubleshooting to find help for common issues.
HP Support does not generally provide free service for out-of-warranty devices.
Our HP Community is not HP Support; we do offer online help free of charge.
