Good to know

HP 936 black ~1,250 pages; cyan/magenta/yellow ~800 pages each.
HP cartridges are regionalized: the same-shaped cartridge carries a different number in other regions, and HP printers reject cartridges sold for a different region (HP Support Community documents a US printer rejecting cartridges bought in Mexico). Moving countries may require an HP-assisted region reset. HP Ireland lists the HP 937 (e.g., 937 black 4S6W5NE) for the same OfficeJet Pro 9125e — the regional counterpart, not interchangeable with HP 936 in a US printer.
Models with an "e" suffix are HP+ enabled: if HP+ is chosen at setup, HP requires "exclusive use of Original HP Ink cartridges for the life of the printer", plus an HP account and an ongoing internet connection. Third-party or refilled cartridges will not work on an HP+-activated printer.
HP states these printers are "intended to work only with cartridges that have a new or reused HP chip" and use dynamic security to block cartridges with a non-HP chip; "Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked." Remanufactured/refilled cartridges that reuse an HP chip are allowed.
