At the time of purchased the store Sales person said the printer is wify enable, but at the time of installation seen this product support only USB. Very next day I visit to shop and told him "You send me the different product". The sales person clearly denied. He said " I do not have any wify support printer, but when I had check there, they have 1 HP printer which is wify computable. At the time of selling that one they showing. When I had chase him and there store manager they completely miss behalf and said me sorry after opening the seal we can not take return back.
Last year May 2020 I had facing so many problem in this printer, that time all India Lock down, On July 2020 when I had register the complained at HP they clearly said this product out of warranty, need service charge and the parts cost. At that time I do not have sufficient money, so I had drop the repairing plan. On April 2021 I had repaired this product when he came he clearly said this is obsolete model please search the bill and tally the warranty through HP side. He support me and guide me "how to check the warranty". When I am check my product warranty there showing warrant laps on December 2019, where as I had purchased this product November 2019.
