Information processing system and non-transitory computer readable medium

A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising:

• acquiring type information indicating a type of a recording medium, the recording medium having a surface defining an image portion and a pressure adhesive toner layer, the recording medium being folded and pressure-bonded with the surface acting as a pressure-bonding surface or the surface of the recording medium acting as the pressure-bonding surface and being overlaid and pressure-bonded to another recording medium;
• and
• presenting predetermined warning information when the type of the recording medium indicated by the acquired type information is a type in which a pressure-bonding strength of the pressure adhesive toner layer is less than a lower limit threshold determined in advance.
