Your Dell Printer Offline message could be caused by a variety of things, such as obsolete printer firmware or PC printer driver software, a hardware issue with the printer's connection to the PC (such as cables or Wi-Fi equipment), or outdated computer software. Additionally, any one of the subsequent three elements may be the cause of this issue. The first one can be the computer turning off the wireless adapter in order to save energy. Alternatively, inadequate network information or an incorrect IP address in the printer settings.
