The Casio CW-100 Disc Title Printer uses direct thermal printing technology. The CW-100 can print titles on up to 40 discs in one of 5 different colors (red, blue, green, silver or black). The CW-100 will not damage your important discs. Unlike other ink systems, thermal prints dry instantly, & the final print will not peel off. Use any font on your system to create custom disc titles. 300 DPI Printing provides sharp, professional results. The CW-100 also provides a unique auto-turn function to print on upper & lower areas of your discs in one simple operation.
