HP - LaserJet M234sdw Wireless AI-Enabled Black-and-White Laser Printer - White & Slate

Hello Jean, thank you for your question! The "s" after the HP LaserJet MFP M234sdw or M234sdwe model number means the printer has an ADF (auto document feeder) that allows you to scan or copy multiple pages. The ADF holds up to 40 pages at a time. The "d" after the model's name indicates that the printer has a duplexer. A duplexer allows you to print double-sided. The "w" means that the printer has wireless (both through WiFi and WiFi direct) and network (or ethernet) capabilities. The "e" (which you are asking about, but not on this specific model) means you can opt-in for the service via the free HP Smart App and get a commitment free trial for HP Instant Ink. You also get a 2nd year of the manufacturer's warranty and advanced scanning features through HP Plus with the "e" model.

Thank you for the question. When setting up the printer, can can opt out of Instant Ink (not accept the free ink/toner trial). If you opt-in and decide that you want to cancel later, you can log in to your account and cancel the service. Note that once canceled, the cartridges will be rendered inoperable and you'll need to replace them with regular retail cartridges.
