All drivers for all printers from all manufacturers are downloadable on their corporate web pages.
So here is yours.
As for which it depends on the user. Global is always newer, but the native drivers are more specific.
PCL is more accurate in lines, but PS is far more robust in color.
I don't have an installation CD with my 7400 and although it installs when connected via USB it doesn't seem to print correctly.
I've set the printer via the control panel to use SRA3 from tray 1 MPT and tray 2 but when I open a picture (any size) on my PC and click "print" the 7400 asks me to load "Letter 11 inch paper". In the "driver" and default printer settings on my PC I select SRA3 paper at photo quality and still it prints at letter size and is back to Letter 11" when I open a new picture.
When I open color management and click the Xerox from the drop down menu it is set to "automatic selection" but doesn't have any profiles listed or associated with it. I can add a profile but not sure what one or if this needs to be done?
I think the basic driver that's installing when I connect via USB isn't very good for Windows 7, theres many drivers listed on Xerox website but not sure which one to choose (Postscript, global, V3, mobile etc..) or even if one of these is the problem.
If you could point me to a driver or color profile which I'm probably missing without an install CD and can be used for Win7 I'd be very grateful.
Thank you so much.
