1- i found media with code RICOHJPNR018, is this the same as RICOHJPNR01? what’s the 8 making at the end? (and not only RICOH, some others too have extra numbers, for ex MCC0038).
2- what’s the difference between RICOHJPNR01 and RICOHJPNR02? 01 is 4x, 02 is 8x?
3- for this (and other media also), do the brand under which the media is sold make difference in quality? there are cheap and expensive ricohjpnr01, is there any quality difference or all the same?
