The LaserJet Pro P1109 uses HP 85A black toner, with a choice of single-cartridge and dual-pack formats. Both stay within the same toner family, so the useful comparison is the number of cartridges in the pack.
Toner Buzz carries genuine HP 85A toner for the P1109. CE285A is the individual cartridge and CE285D groups two, letting you order one cartridge or a pair without changing toner families.
