HP Envy Photo 7830 + HP OfficeJet Pro 8022 ppi errors in photo printing

[Hempf]

Hey guys, 

I've got a problem that neither the hp support, nor I can answer. 

2 weeks ago I've bought an HP OfficeJet Pro 8022 where I had the problem, that on every printed photo I had some stripes over the picture which seem to be in a lower ppi quality. I usualy print in 600 ppi, but those stripes seem to be in under 100. 

Because of that error (and some others), I gave the printer back and bought an Envy Photo 7830 which has exactly the same problem. 

We tried

- different drivers (older driver, compatible drivers from Photosmart C7200 and C309).

- different paper (HP Advanced Photo Paper, Canon Photo Paer Plus Glossy, Canon Photo Paper Pro).

- different apps for printing (LR, PS, HP Smart, Windows Photo and a completely different device - from an iPad)

All photos were printed in highest quality with a minimum of 300 ppi (up to 1200).

Is this a well known HP problem? I don't get it why there's 1:1 the same problem with two completely different printers.

My parents got an HP Envy 5000 series which works absolutely fine. 

Here's a pic (scanned with 1200dpi) where you can see the problem pretty good.

@Hempf

I have gone through your Post and I understand your concerns

Does this issue occur only when printing Photos?

Do you experience the same issue with Photocopies?

Please ensure the printer has the latest Firmware. You can refer to this Link: https://support.hp.com/in-en/document/c02919168

Keep me posted

Hey,

yes, it happens only when I print photos. The issue also appears when I copy something (but due to the lower quality, it's harder to see). 

Firmware is the latest. 

It's crazy that the same error occurs on two completely different printers.

@Hempf

Since the issue occurs while making Photocopies, this is not a driver issue

I suggest you contact HP Support for Service Options

Click on this link - www.hp.com/contacthp/ and select your Country to get the Contact details for HP Support

Thank you

I'm already in contact with HP support but the support also doesn't know how to help me. 

I could exchange the printer again, but I think this is a general problem of HP printers, since this happend on two different models.

So I changed the printer again but the failure is still the same. 

I wouldn't say HP printers suck, but there's no reason why I shouldned. 

HP made a fool of themself when they can't even bring decent photo printers on the market. 

I'm really unsatisfied.
