Canon Printer Shows Online But Won't Print: Here is How to Solve it

It often happens when you hit print but the document disappears from your screen, and the printer makes that familiar noise of printing but results in nothing. You check your computer and it clearly says your Canon printer is online but not printing.

This is one of the most frustrating printer problems but it is a very common issue faced by many users. The printer is on, it's connected, your computer recognizes it, and yet the page just never prints. But the good news is that you do not need to worry anymore as we are discussing the problems and the relevant solutions for the Canon printer not printing.

Why "Printer Online" Doesn't Mean Ready to Print

Most people assume that if their Canon printer shows online, it's ready to go. That's a reasonable assumption but it's not quite how a printer works.

Online simply means your computer can detect the printer and nothing beyond that. It has no idea whether there are errors sitting in the background, jobs stuck waiting, or whether your print job is even going anywhere. A good way to picture it is when your phone shows full signal bars but the page still just spins and refuses to load.

The Most Common Reason: Your Print Queue Is Stuck

If your Canon printer is connected but not printing, the first place to look is the print queue. When canon printer paper stucks, the printer may not print even if it is showing online. In the setting, you can find a list of all the jobs waiting to be printed that are preventing your latest print job from printing.

In this scenario, your new print job joins the same queue and never comes to the front to get printed. The printer just sits there and showing online as it is waiting for instructions.

How to Fix? Go to your Control Panel and open Devices and Printers. Find your Canon printer in the list, right click it and select See What's Printing. This will show you everything that is currently waiting to be printed. Select them all and cancel every single one. Once the queue is completely clear, restart your printer, wait for it to come back online and try printing again.

Canon Printer not Printing Due to Wrong Printer Selected

Sometimes, canon printer show offline or are simply not printing because you have selected the wrong printer. Every time you hit print, your computer sends the job to whichever printer is set as default. If you have connected more than one printer recently then there is a good chance Windows or Mac has been quietly sending your jobs to the wrong one the whole time.

How to Fix it? Open Settings on your Windows and go to Bluetooth and Devices then select Printers and Scanners. You can easily find your Canon printer from the list and set it as the default. Now, find the tab "let windows manage my default printer." You need to turn it off if it is on already. Windows switches your default printer on its own when that is enabled.

On Mac, go to System Settings, then Printers and Scanners, and check which printer is selected when you try to print. It should be your Canon, not any other device listed there.

The Print Spooler Has Stopped Working

The Print Spooler is a Windows service that manages all the print jobs being sent to your printer. When it stops running which can happen after a Windows update, a software conflict, or just randomly, your Canon printer will show as online but absolutely nothing will print. At first, it looks like a Canon printer paper jam issue but it is not actually.

How to Fix Print Spooler Issue? To fix this, press the Windows key and R at the same time to open the Run box. Type services.msc and press Enter. A list of Windows services will open. Scroll down until you find Print Spooler, right click it and select Restart. If it shows as Stopped rather than Running, click Start instead. Once the spooler is running again, clear your print queue the way we described above and try printing.

Your Canon Printer Driver Is the Problem

Other usual problems involve the Canon printer driver not being available and the printer not responding when the printer's spooler is running. The driver enables your computer and printer to communicate and control the printing process. If it gets corrupted, a Windows update quietly breaks it and cuts off the communication. Due to this, your printer just hangs there looking online but not printing or printing the blank pages.

How to Fix Printer Drive Unavailability? To fix the driver unavailability, remove the current driver completely. To do this, you need to go to Device Manager and then select the expand print queues option. If you see many printers there, select your Canon printer. When uninstalling, do not skip the part where it asks you to delete the driver software too. Many people miss that and then wonder why nothing has changed. After finishing all the above steps, you need to buy the original Canon printer model that you can get directly from Canon's official website.

Remove the Printer and Add It Back

The most basic solution is to remove the printer and re-insert it completely new. Your computer's printer configuration can cause minor errors or conflicts over time. It is especially true after software updates, and these aren't always visible as obvious error messages.

On Windows, open Settings and go to Printers and Scanners. Then select and click your Canon printer and remove it. Restart your computer and click Add a Printer or Scanner and let Windows pick it up again. On Mac the process is pretty much the same. Go to System Settings then Printers and Scanners, hit the minus button to remove it, restart and then use the plus button to add it back.

In many instances, there are issues in canon printer software for mac which can be rebooted once you restart your printer or computer. This fresh connection clears out any corrupted configuration and often solves the problem when none of the other fixes have worked.

What If Canon Printer Still Show Online But Not Printing

If your Canon printer keeps showing online but stops printing regularly, it usually points to one of two things. Either the Print Spooler service is unstable on your computer which can happen if there is a deeper Windows issue, or your printer driver is frequently getting disrupted by automatic Windows updates. In that case, check Canon's website for driver updates regularly and make sure your Windows is fully up to date so the system and driver stay in sync.

Honestly, if the issue keeps happening, your setup probably has something specific going on rather than general fixes. Getting canon printer online support is usually all it takes to find what is actually causing it. Most people who deal with a canon printer driver issue that keeps coming back, it is better to take professional help.
