We have several Canon C7260's with imagePass A2 Fiery controllers. Driver that came with the fiery's is version 4.3. Have 2 identical printers on a Windows 2008 R2 print server with version 4.3 drivers. Client workstations that had these printers installed before were on the version and was causing problems. Finishing options not being retained, layout options ignored, etc. Reverting to the 4.3 seems to resolve these issues, however, the client workstations that previously had the 5.0 version keep updating themselves from the 4.3 version to the 5.0 version. Already tried the printer delete utility, and removing drivers from the registry, with restarts in between. Any idea how to completely remove the fiery driver updater from a windows 7 computer?
