There are a few things you may do to see how to get my canon printer back online if it is offline. First, investigate whether Canon has a new driver available on their website. Download and install it if they do. Try removing the driver first, then reinstalling it if that doesn't work. Finally, you might need to get in touch with Canon support if neither of those alternatives work.
Check all of the printer cords first. Make sure the printer and PC are correctly connected with the wires. Next, make sure your network is operational. It is not a printer-specific issue if you are having problems connecting to the Internet. Third, link a Canon printer to Wi-Fi using an Ethernet wire. You can control and troubleshoot your printer with the help of some printer manufacturers' proprietary software. Installing the software is advised if this is the case (your printer may have come with a CD that has the software, otherwise find it on their website).
Cannot print document due to Canon printer offline error on computer. Therefore, verify that the Canon printer is linked to both the local Wi-Fi router and the PC. Next, examine the hardware and software of the printer. Additionally, try restarting your computer and printer and trying printing a page. Here are a few of the most typical problems that printer users encounter.
Cannot print on Canon printer? Here is what to do.
Reprint the file, making sure to select File Print from the menu this time rather than using a keyboard shortcut. After that, pay particular attention to the options that appear; if the drop-down menu displays a printer other than the one you desire, click it to make your selection.
In other cases, the mechanism might be clogged with paper. In most cases, your printer will inform you of this, and all you have to do is open the access panel and remove the crumpled paper. (Again, if you're unsure of where it opens up, see your handbook.)
You can be relatively certain you have a software issue if Windows throws an error yet your printer's own test page prints perfectly. If the printer is unable to print even a test sheet for itself, you should concentrate on fixing the printer rather than the driver or software. If you're lucky, your printer might even send you a test sheet with a decipherable fault number or other message on it.
