HP also has a printer that will print CDs in addition to regular printing jobs at a cost near $100.   I believe this uses a tray as does the Epson. The tray protects the recorded side of the CD. I have seen CDs printed with the Epson and HP and they look very nice.   One complaint about the HP was the software for setting up the CD printing, but label software such as Acoustica works quite well with printing discs. I have also seen discs printed with lightscribe that look good, but one has to use special discs for this purpose. The main complaint has been that the process takes a twenty minutes or more.
