For some reason my sisters computer "lost" it's printer driver (her term). I attempted to reinstall a new driver for her, but discovered that HP has discontinued support for this printer. The only apparent options are these commercial links that I'm not sure I can trust. I'm trying to find a place I can download a driver for this printer or a different driver that works for her printer. Any ideas? She is running Windows XP professional operating system on an older Acer system.
