Some ink from included bottles is used to start up the printer. For details, see: www.hp.com/go/learnaboutsupplies. Commissioned by HP Inc., this Keypoint Intelligence consumer study determined that HP inkjet Tank printers provide the best everyday print quality compared to competitive inkjet tank printers from Brother, Canon, and Epson. Two different inkjet printers were used for each brand. All devices are available in the market and are currently active. Prices range from $180 to less than $400 and all competitive products fall within the same category as the HP printers. The competitors were chosen because they represent the top 80% of the competitive landscape for 3:1 and 4:1 wireless A4 inkjet tank printers under $450 USD, as reported by the IDC Quarterly Hardcopy Peripherals Tracker-Final Historical CYQ2 2024. Samples were printed in the United States and then reviewed by consumers in the US, the United Kingdom, and Japan. Details: www.keypointintelligence.com/hpbesteverydayprintquality
