If you've ever searched "how to connect to printer" at 11pm with a deadline tomorrow, you know the exact feeling. The printer is sitting there. The light is on. The router is blinking like it just learned Morse code. And the only thing printing is your frustration.
I run quality and brand compliance for a mid-size office products company. I review every deliverable before it goes out—roughly 200 unique print jobs a year. In Q1 2024, 6% of our first deliveries failed internal color tolerance checks. The culprit? A Canon Pixma TR4720 wireless all-in-one printer that kept dropping off the network at the worst possible moment.
That's when I stopped blaming the machine and started measuring the real cost of "it'll work eventually."
The Surface Problem: "My Canon Printer Won't Print"
People assume the Canon printer is broken. After several years of auditing print workflows, I can tell you it's usually not the printer. It's the setup.
The most common issue with a Canon Pixma TR4720 is a network mismatch. The printer connects to 2.4GHz networks. Your phone or PC might be on a 5GHz network. They're both "the same Wi-Fi" to you, but to the printer they're invisible to each other.
If you're trying to set up a Canon printer for the first time, the fastest fix is:
- Forget the network profile on your phone or computer.
- Connect to the 2.4GHz band—often the one your router labels without "5G."
- Run the Canon PRINT app again instead of the browser setup.
- Turn off any VPN before you start. A VPN will block local network discovery even if you and the printer are in the same room.
That sounds simple, and it does work. But it's still only the surface.
The reason so many "how to use Canon printer" guides get it wrong is they stop at the buttons. They don't ask what happens after the connection fails.
The Layer Underneath: Every Quick Fix Has a Cost
Here's where I get called paranoid. I'm fine with that.
In late 2024, I specified a replacement for the TR4720. The first quote for a used unit was $119 plus freight. The vendor's invoice had a line for "standard ground." I didn't think twice. Then the freight company reclassified the box at pickup. The weight was right, but the dimensions put the density below the class threshold. The carrier added $48 to the invoice. The used unit didn't have a warranty, so I asked the vendor to cover it. They said no. (Note to self: always ask for delivered price, not base price.)
It wasn't the money that stung. It was the surprise. We had budgeted a simple swap, and instead we got a freight reclass invoice and a long night on the phone.
Trust me on this one: a "delivered price" quote is not the same as a "will not go up" price. That's why I use a freight class calculator before I authorize any equipment shipment now. It gives me a ballpark for the real cost before I commit.
Why Your Laptop Says "Offline" and What It's Really Telling You
If you've seen "printer offline" on your screen, that's not a printer problem. It's a communication problem. Windows and macOS handle printer discovery differently, and both can fall back to a network profile that doesn't match the printer.
The deeper problem is that most printers were designed for a 2.4GHz-only world. The Canon Pixma TR4720 wireless all-in-one printer supports 2.4GHz Wi-Fi. If your router broadcasts a combined SSID, your phone may connect to the 5GHz channel while the printer connects to the 2.4GHz channel. Same name. Different network. No conversation.
In my experience, this is the #1 reason a Canon printer "won't connect." The fix is to split the SSID or assign the printer to a static 2.4GHz profile. That's not something the quick-start guide tells you. It's also not something a support tech can diagnose over the phone if you don't know your router's login.
The Cost of "Probably Working"
The bigger cost isn't freight. It's certainty. Or the lack of it.
In March 2024, we paid $400 extra for rush shipping on a large-format scanner. A supplier part had failed, and we had an event in six days. The normal delivery window was eight business days. The rush package got it there in three.
To be fair, $400 is hard to swallow. But the alternative was missing a $15,000 client event. You can do the math. Or you can just accept the fact that in an emergency, you're not paying for speed. You're paying for a confirmed date.
So glad we paid the expedite fee in that March job. If we had gone standard, the scanner would have arrived after the event—and the event was not reschedulable.
I used to think expedite fees were a scam. Then I saw how many moving parts have to align for a rush order to actually arrive on time. It's not just "put it on a faster truck." It cascades through inventory, picking, carrier pickup, and tracking updates. That certainty is a feature, not a tax.
Using a Present Value Calculator Before You Replace the Printer
This might sound like a stretch. Stick with me.
When the Pixma's parts started failing last year, the repair quote was $219. A new Canon Pixma TR4720 wireless all-in-one printer cost $129. A lot of buyers would call that a no-brainer. I almost did.
But then I ran a present value calculator with the actual cost assumptions: ink costs, expected page yield, warranty coverage, and the probability of more repairs. The repair had no warranty. The new printer did. When you discount future costs back to today, the repair ended up costing about $87 more than the replacement over two years.
Per Canon's U.S. warranty statement (accessed April 2025), the PIXMA series includes a one-year limited hardware warranty. Verify current terms at Canon's official support page before making a decision.
Page yields on Canon ink cartridges are based on ISO/IEC 24711. That's a standardized test, not a marketing guess. Include those numbers in your calculation.
The present value calculator doesn't tell you which product is "best." It shows you what a future cost is worth today. If you're comparing an upfront payment against ongoing maintenance, it's the only fair way to decide.
The Fix, Briefly
If you're stuck with a Canon printer that won't stay connected, don't just restart the router. Walk through the network band, disable the VPN, and use Canon's own app. If the machine is under warranty, let Canon handle the repair. Don't open the case yourself.
If you're shipping anything bigger than a small box, use a freight class calculator before you approve the quote. Know the density and class in advance.
If you're deciding between repair and replacement, use a present value calculator. Include ink, paper, support time, and the value of having a working machine when you need it.
I get why people skip these steps. Budgets are real. Time is real. But the hidden costs keep coming back.
Bottom line: The best way to use a Canon printer is to understand what it costs when it isn't working. The cheapest purchase at the register is not the cheapest purchase in total. And when a deadline is on the table, certainty is worth a premium.
