This is exactly what I had wanted to do. I don't think what they told me was an issue of not wanting to take the time. I think they simply didn't want us doing it, for whatever reason.
Now, if I understand you correctly, you had the old driver version on one HD, and the new driver version on another. So you found the custom presets folder in the old driver, copied it, and pasted it into the same place in the new driver. Is that essentially the procedure? Most important, where in the driver package did you find the custom presets folder and how? Was this on Mac or Windows?
Hi Mark,
These are the paths to both of the Custom Preferences for the Mac Driver (Custom Paper Sizes and Custom Presets). They are not in a Driver Package, they are Preference Files in the User Library. I recalled doing this back in 2010 when I was setting up the SP9900. I had to find a way of using the Custom Paper Sizes I had created previously for the SP7600 printers. Eventually, through considerable trial and error as well as some help from the Apple Forum I was able to get the job done. When I run up against these sort of issues I always document the procedure that finally led me to a resolution. Following are the Custom Prefs I used and where to find them. Once I have installed what I believe to be the proper, working Prefs, I open Disk Utility and run First Aid. I then restart the Mac and test the driver.
For the Custom Paper Sizes -- User > Library > Preferences > com.apple.print.custompapers.plist
For the Custom Presets -- User > Library > Preferences > com.apple.print.custompresets.forprinter.EPSON_SC_P7000_Series.plist Of course the printer name will reflect the printer you are using.
As I do, I think it's a good idea to create a folder containing all of this information for future consideration. Of course once you have located the proper pref and saved it in a separate folder, you will have to trash the one you don't want and replace it with the "good" one. Not sure where you will retrieve the "good" one from, but since I have 3 BootClone drives I had no problem finding a pref that I knew should work, and it did. My advice would be to save the two Custom Prefs that you know are working as expected and keep them for future use if necessary. The two prefs I have referred to here were actually created with the SP9900 driver and they work very well with the SC-P7000 driver as well. One thing to keep in mind is this. When you are looking for a "good" Custom Pref, click on the Pref and see how much information it contains. If it's almost empty that means you would have to recreate all of the Custom settings you want within the driver itself, which might take considerable time obviously. Oddly enough the Custom Paper Sizes were maintained, but the Custom Presets were over-written by the new driver. Not sure why, but I am thankful that I only had to fix one of them.
Hope this helps Mark.
