HP1 3BZ Great Gaddesden, Amaravati Monastery, St Margarets.
It is a discontinued HP product. On windows 11 it doesn't work but it should work with Windows 10 maybe. There is a report from an HP Community user who got the C5280 working on Windows 10 64-bit by installing the printer driver from Optional Updates. It may suit someone with an older compatible computer or someone who knows how to install legacy printer drivers. Collection only.
