I’ve had mine for 4 years, and are considering changing it right now, having said that it runs perfectly so might just hang on to it for another year or so.
Would be nice to have the new faster one but not an absolute necessity as this one does everything it needs to do.
Be sure to take out an extended warranty, I’ve had mine with the official HP providers (not sure I can say the company name), and have been very very happy with their response times & knowledge.
Might be expensive, but same applies to all the other printers….expensive if you never need to call upon their services, but if you do… well worth every penny!
