The HP LaserJet MFP M140we uses a single HP 134A cartridge — one SKU, no decisions

The M140we is about as frictionless as mono printing gets — one HP 134A Black LaserJet Toner Cartridge, no high-yield alternative to weigh, no drum unit to schedule separately, no color cartridges to track. It’s the printer-equivalent of a single-speed bicycle: you just ride it until you need more toner, then you buy the same thing again. Perfect for a low-volume desk where the last thing anyone wants is a consumables decision tree.
