How to connect printer to phone with USB 045490505

First, you shall have your USB OTG adapter, which connects USB peripherals (like your printer) to the phone system. The type of OTG adapter needed depends on the port configuration of your phone; if it is a USB-C port, join this with a USB-C OTG adapter; on the other hand, if the port is micro USB, then go for a micro USB OTG adapter. Then insert the printer into the USB port of the OTG adapter and connect it to the phone. After that, you will need to check whether the printer works as a plug-and-play printer and can recognize the printer from your phone automatically, or you need to install a printing app specific to the brand (for example, HP Smart, Epson iPrint, Canon Print).
