Hello, I am Christina Pine. I am a printer offline executive and freelancer. There may be different reasons why your Epson printer is offline. Common problems like printers not properly connected to network or device, there is an issue with printer drivers, or communication mistakes between printer and system, and also sometimes printer status might be set to offline mistakenly. It is also conceivable that the printer's status has been changed to offline. To resolve the issue, first check the printer's connection to the network or system and confirm the printer driver is installed properly; if not, upgrade the drivers.
