When a printer says “offline,” it means that the printer is not capable of printing. Usually, the reason is low toner or ink, paper jams, or loose or defective cables.
Printers go offline due to power surges and sags, corrupted files in the print queue, paper jams, an empty toner cartridge or paper tray, bad components in the printer itself and interference by remote users. Only some of these generate unique error messages.
Most printers generally do not work offline, although some with a copy function may copy when offline. A printer that is offline is either not connected to a computer or not recognized by the computer and is unable to communicate or receive print commands from the device.
