My new HP printer has the heads in the printer rather than the cartridges. Which seems like a very backward step to me, especially for people like me who use their printers about 4 times a year...
Oh, that is so bad. I moved away from Epson specifically because of their poor head-in-printer design, and now HP is doing it too?!... So bad.
I still remember my very first inkjet printer, an Epson Stylus 800, B&W, which would use so much ink just to try (and fail most times) to unclog the printing head. What a nightmare. Eventually the head broke and I was asked 90% of the printer cost for a repair. Those must have been early/mid 90ies.
