I don't know which printers you have tried, in my opinion and
experience only the printers with pigmented ink (like Epson 2100,
4000, 7600, 9600) could be used, eventually sprayed with Lyson Print
Guard or similar. If you are printing to get black & white prints,
you might better use only black inks like those from MIS Associates

However, the cause of the fading could also be ozone in stead of
UV-light, especially if there is a source of ozone (like laser
printers) nearby. At our photographic department we have had a
similar problem, that turned out to be caused by the ozone that was
emitted by our flash units. with best regards,
