Ok so the Pocketjet PJ-663 manual says,
“- Avoid contact with Diazo (blueprint), carbon-less, or cast-coated papers.

- Avoid contact with vinyl or acetate materials, such as many notebook or report covers.

- Avoid contact with organic solvents, oils, and ammonia.

- When using a coloured marker, be sure to use one with a water-based ink. If you use a solvent-based marker, it may darken the paper.”

So like, I can watercolour just fine, but not acrylic paint them (fine by me).
The laminate is made of PET, which is polyester?
Is polyester “cast-coated”?
