Unfortunately using third party toner products is often problematic.
And likewise, using vendor (HP) toner is indeed expensive.
However, you may be able to save some money by joining HP's Instant Ink and Toner subscription plan.
I use HP inkjet cartridges and have more that halved my inkjet cartridge costs previously purchased via local big box stores. And, interestingly enough, the subscription sent HP cartridges seem to last forever....
My last set of big box store cartridges cost over $120 - tended to last around 9 months with another $60 or so being needed for an individual color cartridge from time to time. Annual cartridge cost previous being $180/per year.
Current subscription plan running $7 - $8 per month. Less than $100.00 per year.
Down side being that I subscribed to a 100 pages/month limit which means that every 10 pages over adds a $1.00 to the monthly subscription rate. I can easily change to more pages/month if necessary. And I am much more careful about what I print and not "waste" pages.
My suggestion is to take a close look at how much money buying off-the-shelf HP toner would cost you and then compare the pricing to a subscription plan. Take a look at the printer's admin pages/reports to get a sense of how many pages are printed each month.

Just read all the fine print etc.. Do some math and see if the subscription plan will be benefiical to you.
Overall: print quality will be much better and the printer itself will be a bit more "protected". Barring any existing issues due to the previous low quality toner. (Which may have voided any printer warranty.)
Just offering a lead....
