If only I had checked here before I purchased my HP printer as it's clear everyone is very unhappy!I purchased an HP deskjet in March. I had issues from day 1. I did all the troubleshooting and nothing worked. I've used it four times since March and every time I've tried to print it has taken about 5 attempts to get the printer to work and then when it does print I get one line at the top and then the rest is a big block of ink (ie a waste of expensive ink!)My fourth attempt was today and I did the whatsapp assistance (which by the way is long and boring) and went through all the troubleshooting I've already tried. They asked to see a screenshot from my app and flagged that my ink was low (it wasn't close to running out so not enough to stop it from printing) and I pointed out the reason it is so low is because every time I print I get blocks of ink so the fact I've only used it four times means there should be plently of ink.After doing this long and boring troubleshooting with HP, they said they would send a replacement. I told them I didn't want a replacement and wanted a refund. Then they kept me waiting ages again so I called Argos (where I had originally purchased it but their help option said to speak to HP) and within 2 minutes they had issued me a refund and organised a collection between 2 and 9pm! If only it was that easy with HP. Safe to say, my next printer will NOT be HP. Nor will any future purchase. Awful customer service and their 1 year warranty clearly means nothing.
