For the most part, no. The majority of portable phone photo printers use some form of ink-less technology. For example, zero-ink printing technology uses special paper with advanced heat reactive molecules inside which change color when heat is applied. In this way, it's actually the paper which plays the biggest part in the printing process in many modern devices. This is also why the printing paper often costs more than people expect. However, it is also worth noting that there are exceptions which still use some form of ink cartridge to print images. Make sure to check which kind of printer you are buying so there aren't any mistakes or surprises along the way.
