Some printers offer online sharing of pictures through printers to other printers. It is only possible through the applications; all you have to do is select an image you want to print through the portable printer. Now, select the share option, and ask your friend to allow their printer to print the same picture remotely as well. This feature is available in only a few portable photo printers. Moreover, it is only feasible when the printers are by the same manufacturers and of the same model.
