Canon Printer Printing Slow — Speed It Up
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
When your Canon printer suddenly starts taking several minutes per page, it's incredibly frustrating, especially when you have important documents to produce. The good news is that this issue almost never requires an expensive repair or replacement—it's almost always something you can fix yourself in under thirty minutes.
Slow printing on Canon printers typically stems from software conflicts, memory issues on your computer, or settings within the printer itself. We'll walk you through the most effective fixes, starting with the easiest solutions and moving to more technical adjustments if needed.
How to fix it — step by step
- Clear the print queue on your computer. On Windows 11, open Settings, navigate to Devices, then Printers and Scanners, find your Canon printer, and click it. Select Open queue and delete any stuck jobs by right-clicking them and selecting Cancel. On macOS, go to System Settings, Printers and Scanners, select your Canon printer, and click Open Print Queue to remove any pending documents. A stuck job in the queue can cause all subsequent documents to process slowly or hang indefinitely.
- Restart your printer and computer completely. Power off your Canon printer using the power button and leave it off for at least sixty seconds, then turn it back on. Simultaneously, restart your computer and allow both devices to fully boot before attempting to print again. This clears temporary memory caches in both devices and often resolves communication delays between your computer and printer.
- Check your computer's available disk space. On Windows 11, open File Explorer, right-click This PC, and check how much free space remains on your C drive—you need at least ten to twenty percent free space. On macOS, click the Apple menu, select About This Mac, then Storage to view available space. When your drive is nearly full, printing slows dramatically because your system cannot write temporary files needed for the print job. Delete unnecessary files, empty your trash, or consider upgrading your storage if you are below ten percent free space.
- Update your Canon printer drivers. Visit the official Canon support website, enter your printer model number, and download the latest drivers for your operating system. On Windows 11, run the installer and follow the on-screen prompts to completion, then restart your computer. On macOS, download the DMG file, open it, run the installer, and restart your Mac. Outdated drivers frequently cause slow printing because they lack optimizations and bug fixes that improve performance.
- Clear the printer's internal memory and cache. On your Canon printer's control panel, access the Settings or Maintenance menu (the exact name varies by model), then look for options like Clear All Settings, Reset Network Settings, or Delete All Jobs. Select the option to clear the job queue and temporary memory, then allow the printer to restart automatically. This removes any corrupted data stuck in the printer's memory that could be causing it to process pages slowly or incompletely.
- Check for Canon printer firmware updates. Visit Canon's support website, find your specific printer model, and look for available firmware updates in the Drivers and Downloads section. If an update is available, download it to your computer following Canon's instructions—some updates require you to transfer the file to the printer via USB, while others can be installed through the printer's network settings. Firmware updates often include performance improvements and fixes for processing speed issues that Canon has identified.
- Adjust print quality settings to a lower resolution. Open any document you want to print, go to File then Print, click Printer Properties or Preferences, and look for Quality or Resolution settings. Temporarily reduce the setting from Best or High Quality to Normal or Draft mode, which processes pages much faster because the printer uses less memory and processing power. This is an excellent diagnostic tool—if your printer suddenly prints at normal speed in Draft mode, you know the issue is related to processing complex graphics or high-resolution output.
- Test the printer connection and check for interference. If your Canon printer connects via Wi-Fi, verify that it shows a strong signal on the printer's control panel display—weak wireless signals cause severe slowdowns. Move your printer closer to your Wi-Fi router if possible, or eliminate interference by keeping the printer away from microwaves, cordless phones, and other wireless devices. For USB-connected printers, try a different USB port on your computer or use a shorter, high-quality USB cable, as poor connections can cause the printer to repeatedly re-initialize during print jobs.

Frequently asked questions
Why did my Canon printer suddenly start printing slowly when it worked fine yesterday?
The most common cause is a stuck print job in your computer's queue or a corrupted temporary file in your printer's memory. A Windows or macOS update, new software installation, or even a power interruption during a previous print job can trigger this issue. Clear your print queue and restart both devices—this resolves the problem in the majority of cases.
Should I replace my Canon printer if it is printing slow, or is it usually fixable?
Slow printing is almost never a hardware failure in modern Canon printers and is virtually always fixable without replacement. The issue resides in software conflicts, driver problems, or temporary memory issues on either your computer or the printer itself. Only after trying all the steps in this guide should you consider professional service or replacement.
Does printing in Draft or Black and White only mode really speed up my Canon printer?
Yes, significantly—Draft and Black and White modes disable color processing and reduce resolution, which can increase printing speed by fifty to eighty percent depending on your document. If your printer prints quickly in Draft mode but slowly in Best Quality mode, you know the slowdown is related to processing graphics or color data, not a hardware problem. This insight helps you determine whether the issue is your computer's performance or your printer's capabilities.
I have tried everything and my Canon printer is still printing slowly—what should I do next?
At this point, the issue may be a hardware problem with your printer's processing unit or printhead that requires professional diagnostics. Consider contacting a certified Canon service center or booking a remote diagnostic session with a qualified technician starting at forty-nine dollars to identify whether repair or replacement is necessary. If your printer is out of warranty, comparing repair costs against a new printer's price is also reasonable at this stage.
