I need to print from my Galaxy A7 lite tablet. My question is, is it possible to connect a tablet to a printer with a USB? I have a mobile wifi hotspot that is sometimes unreliable so I want to save myself the frustration when the wifi is sketchy.
it is possible, but printer will need to support OTG and your galaxy needs to run printer service
here are printers from HP which supports OTG printing
HP Color LaserJet Pro MFP M176n Printer
HP Color LaserJet Pro MFP M177fw Printer
HP HotSpot LaserJet Pro M1218nfs Multifunction Printer
