You may not be trying to print, but Excel deals with the driver internally to see how to configure the data anyway - I used to have two networked printers at my work with very different drivers, and if I formatted a spreadsheet it would do it according to the driver specs for my default driver - if I then switched printers to print, often things like margins came out wrong. (Have two new printers now, both the same brand and similar in other ways and I don't have this problem anymore.)I have updated the printer driver to the newest version, but it has made no difference. I don't see why this would affect Excel anyway I'm not trying to print anything. Is there an update to Excel I could get to fix this or something similar?
