|Printer can be connected to a host computer and then shared over a LAN. Where and how is the printer currently connected?|
If you have it connected directly to a USB port on a computer you may have it set up wrong. Might be easiest to remove the printer from Control panel> Devices and Printers. Then use Devices and Printers to add a local printer.
Normally USB printers must have the drivers and sometimes other software installed prior to making the USB connection. If you have installation disks for the printer I suggest you just use those disks to reinstall. Follow the prompts and don't connect the printer until instructed to do so.
