Mrs. Stratman gets her work rota as an Excel spreadsheet, withh lots of coloured cells and so on. Our printer is monochrome, so when it's printed the output can be black text on a dark grey background. Not very readable. I've tried and failed to find a way to print just the data without the colours, just black on white. The printer driver (Samsung ML-2525W) doesn't have the option, neither does LibreOffice have the equivalent of Excel's Page Setup, which offers a Black and White option, or if it does I can't find it. Is there a way to print a colourful Excel spreadsheet from LibreOffice in just black and white?
