The HP 1200w NFC/Wireless Mobile Print Accessory is a tiny accessory compatible with most HP laser and inkjet printers. It brings wireless and NFC printing support to these classic printers, which enables users to print documents, images etc. directly from their mobile devices and laptops including Chromebooks.
As you know, Chromebooks don’t support classic printers. For printing on a ChromeOS device, you need to connect it to a web-enabled printer or use the ‘Google Cloud Print‘ service which allows users to print using a classic printer. For GCP, the classic printer must be connected to a separate Windows or Mac computer.
In short, the HP 1200w accessory easily converts your classic printer to a web-enabled printer. The following video demonstrates its setup and working:
Once completed the above installation, you can add your printer to GCP and start printing from any compatible mobile device or Chromebook. Watch this video for GCP setup process:
Apparently, the NFC printing support on HP 1200w is limited to HP devices only, so must verify compatibility with your device before purchasing.
