Standard vs. XL — which should you buy?

HP 134A or 134X cartridges come in standard and XL (high-yield) sizes. Standard cartridges cost less upfront; XL cartridges cost more upfront but typically print two to three times as many pages, so they usually work out cheaper per page if you print regularly. If you print only occasionally, a standard cartridge may suit you better, since toner can degrade before you use up an XL cartridge's larger capacity.

Standard and XL HP 134A or 134X cartridges are physically and electronically interchangeable in HP LaserJet M209dw - you can mix a standard black with an XL color cartridge, or switch sizes the next time you reorder, with no printer settings to change. For the full cost-per-page breakdown and when each size makes the most sense, see our guide on standard vs. XL cartridges.

How to check which cartridge is currently installed in the HP LaserJet M209dw

Most HP inkjets show installed-cartridge status on their own screen or through HP Smart software: check Settings → About or Supplies on the printer, or open HP Smart's printer status or maintenance tab - both typically list the installed cartridge part numbers alongside an estimated toner level.

If your HP LaserJet M209dw doesn't have a screen, remove the cartridge from its carriage - the part number (for example, HP 134A (W1340A)) is printed directly on its label. Compare that number to the compatibility table above to confirm whether you have the standard or XL version before buying a replacement. See our guide on finding your printer model number if you're not sure exactly which HP LaserJet M209dw variant you own.

HP LaserJet M209dw Toner FAQ

The HP LaserJet M209dw uses HP 134A or 134X toner: HP 134A (W1340A) (standard) or HP 134X (W1340X) (XL).
Yes. HP 134A (W1340A) and HP 134X (W1340X) are physically and electronically identical except for toner capacity - the XL version simply holds more toner and lasts roughly two to three times longer per cartridge. You can install either one in the HP LaserJet M209dw without changing any printer settings.
Usually yes, for a while. Laser printers like the HP LaserJet M209dw typically keep printing for some time after a low-toner warning first appears, since the warning is an early estimate rather than an empty-cartridge cutoff. Print density may start to fade before the printer actually stops.
