1. A system comprising:
a printer configured and arranged to form a symbol on a surface of a material using hot melt ink;
a laser processing subsystem comprising a laser and an optical assembly; and
electronics communicatively coupled with the printer and the laser processing subsystem, the electronics being configured to generate a laser beam from the laser and convey the laser beam, using the optical assembly, onto an area encompassing at least the hot melt ink forming the symbol, thereby increasing rub resistance of the hot melt ink on the surface of the material by remelting the hot melt ink forming the symbol.
