Thanks guys for the replies. I only bought the printer to hook up to our 'old' Win98 PC that is kept as a spare (not enough memory for 98SE). I did three things to get it working (BIOS settings were OK) but don't know which one or more did the trick.[list=1][*]Although I'd previously tried a bi-directional cable that I knew worked, I changed to a USB cable connection to the main PC[*]I removed the empty colour cartridge and reinserted it. Obviously it doesn't print colour but the warning light has gone.[*]I switched the printer on before the PC. Previously, although the printer was installed, the PC wouldn't recognize the connection but now it seems to.[/list=1]
At least I now know it's worth buying new cartridges. Thanks again.
