The information should normally be located under the "Printing Technique" tab. In this case, HP claims a print performance of 1000 pages with ~5% coverage.

HP Combopack 303 (M, C, Y, BK, Tinte)

With the 9012e they work, the e should not matter with the original cartridges. I think the e only stands for the fact that hp+ is possible.

Well, I can't answer the question for sure: coloured prints need different ink. I had to buy yellow first, but 2 packs of 250 sheets are certainly enough.

Yes, but it's hard to get. idealo might help.

According to the search query at HP on your printer Office Jet Pro 8710 https://store.hp.com/SwitzerlandStore/Merch/Ink-Toner-Paper.aspx?query=HP%20OFFICEJET%20PRO%208710%20ALL-IN-ONE-DRUCKER&product=D9L18A&type=printer&model=HP-OfficeJet-Pro-8710-All-in-One-Drucker-Tinte 953 and not 963 cartridges are listed as accessories. You can find these cartridges at digitec under https://www.digitec.ch/de/search?q=%20HP%20953 The cartridges with XL as a suffix have a larger filling capacity and are, on balance, cheaper per printed page. However, this is only the case if you print regularly. If you print infrequently, there is a risk that the ink will tend to dry out or stick together, resulting in poor print output. Recommendation: - Buy cartridges without XL if you print infrequently or if the printout is poor due to ink drying/sticking. - Buy cartridges with XL if you print regularly, then daily or almost daily use will prevent drying out.

Apart from the paper, I got the following cartridges as part of the kit: Yellow: 3JA25A / Magenta 3JA24A / Cyan 3JA23A. I can't judge whether they contain 114ml each but maybe you find the required information based on the article number mentioned. Good luck. Heinz
