I have Mac ox, 10.11.6 version and a HP OfficeJet 7510 printer. I get yellow horizontal line on any image I print up. A little while ago I also bought a Macbook pro, refurbished. 10.14.3 Mojave version. I was able to print clean images at first (same printer) but shortly the lines returned. I've tried printing from Preview, from google's My Drive, from Word, from LunaPic. The lines are haunting me!
Whassup?
It is obviously a printer error and not a computer software error.
Have you run all the printer maintenance routines.
HP printers usually come with the HP Utility which will allow you
to run these routines.
System Preferences> Printers & Scanners> Print> Options & Supplies> Utility > Open Printer Utility.

As it is a persistent problem using two different macs and different applications it points to a fault with the
printer.
Go through the cleaning and alignment routines again.
Open up your printer and take to the cartridges and have a look at the physical condition of your
printer and clean out any clumps of ink or dirt.
Have you asked HP about possible causes.
I've done all that and more, still the lines. I use non-HP ink cartridges, so my next move is to take those out and replace them with HP cartridges. If that doesn't work then I'm getting a new printer. Any suggestions on the kind I should buy?
No, I went through the process at the three different levels and the lines are still there.
the horizontal yellow line!
