The Heavy-Duty Office Powerhouse That Faxes, Feeds, and Frees Your Budget.
Meet the HP Smart Tank 790 All-in-One (4WF66A) – the undisputed king of the Smart Tank lineup. While other printers handle light duty, this machine devours heavy office workloads with a 35-page Automatic Document Feeder (ADF), built-in fax, and ultra-low cost per page that will make your accountant smile.

Stop feeding paper one sheet at a time. Start feeding your business growth.
Q: What makes the HP Smart Tank 790 different from the 750 or 615?
A: The HP Smart Tank 790 (4WF66A) is the flagship heavy-duty model with three major upgrades:
Q: Does the HP Smart Tank 790 have an automatic document feeder?
A: Yes. The HP Smart Tank 790 comes with a 35-page ADF that lets you scan, copy, or fax multi-page documents automatically – no standing over the machine feeding one page at a time. Perfect for processing contracts, receipts, or application forms in bulk.
Q: Is the HP Smart Tank 790 good for a law firm or hospital in Nigeria?
A: Absolutely. Law firms need fax for court filings. Hospitals need ADF for patient records. Both need ultra-low running costs. The 790 delivers all three – plus wireless printing from any device – making it the most complete office printer under its price range in Nigeria.
Q: How much does it cost to print one page on the HP Smart Tank 790?
A: With the refillable ink tank system, your cost per black page drops to approximately 3–5 kobo – up to 80% cheaper than using cartridge-based printers. One set of bottles prints thousands of pages.
