Sir,
Let me provide a little generic info on inks for laser print finishing.
The ingredients, properties built into an ink formulation designed specifically for laser imprint go much beyond the type of wax. It involves the resin types in the vehicle system, solids content, VOC %, pigment types and the inks rheology to name a few. They must be designed to be laser compatible.
Further, the variation in temperatures between different laser equipment varies widely. Dwell time and even pressure are more variables that are not constant.
Further yet, coated paper through a laser printer even poses more chance for failure versus most laser work that is printed on offset uncoated stock.
So as you can see, with such little information not given, it is not practical for myself or anyone to provide a valid assessment.
At least I hope you now realize the factors and variables involved that influence laser imprinting failure or success.
