How to choose printer/scaner/multifunctional when you don't know beforehand how do they do their job

The question is more not to a community, but to a HP, so would be nice if someone from HP read this.

As the question states - I want to buy a multifunctional printer, but I don't know how well does it perform. The thing is - I already bought and returned 2 printers (not HP) because they just print terribly (don't want to go into details, just quality is bad - my 5+ year old 50eur worth Samsung does it a lot better). I am surprised that there is no way of knowing the quality of printing/scanning for each printer before you buy it. I mean there are only technical details, but why there are no sample prints/scans? Even reviews on YouTube are do now show the quality of printing (or, rarely, just a brief view from afar of the printed page where you cannot see how bad/good is that.

Maybe someone has a samples for those printers:

1. HP LaserJet MFP M234sdwe

2. HP Laserjet Pro M140we 7MD72E#B19

I would like to see scanned image (not PDF or something that reduces quality of scan, but plain old PNG image) of printed page. Thanks in advance for anyone who would respond to that.

Likely the answer is that because most users give more thought to their morning coffee order than they do to the purchase of a printer. Plus lab generated output will likely be better than what a consumer will produce and that will generate a lot of complaints when it is a settings issue and not a problem with the device. On higher end graphics products you can typically get a sample but sadly the same is not true for entry level consumer products.
