What Does Printer Offline Mean? Why Is My Printer Offline?
The printer is an output device connected to your computer. A computer works well without a printer, but if you want to print out files and documents, you must have a printer installed with your computer. A printer can be connected to your computer through a wire or a cable, but in most cases, it is easier to connect it online with the computer so that you do not need any wire for connection. A printer does not have a USB or cable space in it.
Nothing is the biggest disaster than a disconnected printer in an office. Imagine that you have completed your document, and now it is ready to be submitted. You have selected the print option, and half of the pages are printed in the printer that goes offline. It is a very frustrating experience, and the printer needs to be fixed at once.
There is a possible range of problems that might have occurred with your printer.

The windows installed on your computer often give the possible solutions that you can try.
Connection And Power Problems
