... I've made this some 20+ years ago with a common thermotransfer-printer -- i think this was an Okimate 20 with a colour head.
The wax was etch-resitant, but for better stability I've remelted it after printing with a hot-air gun.
Most transfer-printed PCB's I've seen the last years were made with laserprinted toner on a thin sheet of (glossy) paper and transferred on the PCB with an iron ... but this methode is not 100% light-tight, so I'm 'laserengraving' my paint-coated PCB's and etching them ...
