We have a 7760 DN and have recently run into a problem with colors printing inconsistently. The 32 bit ones will print as they should. The Windows 7 64 bit ones however, are printing much more muted. I have tried reinstalling the printer with the Windows PostScript PPD Driver Files - 32/64 bit driver but it didn't change. We are not having this issue on any of our other printers. Any ideas?
why not try the latest global drivers , that drivers you posted seems a little bit outdated :)
i posted the latest versions .32 of the global drivers earlier in the print section...
