Oh I already know that I had the wrong paper type and was using too much ink, but, based on my moms old printer, that was the best I could come up with. Between the wet ink (again, was more of a "me" problem) and the fact that we were using a TON of ink on small amounts of covers printed, I started getting better results (and not being yelled at at home was a plus) from the printers at college and work. To each their own on which way they want to print, but inkjet would not be my choice.
Mom has a new inkjet now (oh thank God), and when she is printing images for her work (again still printing on the highest ink usage settings) there are times where a straight black line is present.
I am not talking about "repeatable black lines", as that is a drum issue on laser printers,

It's more of a one and done to never repeat for another 50 prints type thing

Smudges for the win, *facepalm
But when that now happens on a $10 (per page) papersource, that really sucks.
Would love to switch her to a laser printer as well, but yeah... laser printer ink is not edible

Complications on both sides, for sure, just saying that the OP shouldn't be locked down to one type of printer when looking to drop $400 AUD
