I believe it is compatible with Windows 98 they are several operating systems that it is compatible with it also requires minimum system requirement like Intel Pentium, Celeron, or a compatible processor.
That sounds like one of the older printers and Windows stopped supporting windows 98 so it might not work anymore but if it is older they might still have there drivers if not look on the internet for the drivers. You can usually find them fairly easy just type that into google
Yes! The majority of new products you can use with old windows operating systems as long as your computer has the specifications that are needed. For example the right amount of RAM and the right proccesor speed. You shouldn't have any problems using a newer printer with an older operating system
