What is the fix for the error message, 'Printer is offline'?

There could be many reasons for this error. I have a Canon MX430 series printer.
I could print earlier to this printer via Wi-Fi connection and probably after a Windows Update (usual suspect for something that breaks) I started getting the message, "Printer is offline". I know that the Printer is on and is connected to Wi-fi. Then what is the problem. The device troubleshooter in Windows 10 Professional could not fix it.

I tried to add the printer and to my dismay, I could not find the printer to add.
Then I tried to manually install following these steps.

Voila, I regained by ability to print to this printer. Do you know what? The Add Printer dialog find a networked printer. I am not what the code behind this search printers.
 

How do I make my Canon MX432 Printer work in my computer with Windows 10 OS?

Now that people are downloading / installing Windows 10 (some thing like 75 Million users in August alone), you will need to make sure that the software and hardware you had earlier works in this new environment. While Wi-Fi connectivity is important, to be able to print to a printer is equally important despite the expensive cartridges.

Canon MX 432 is a pretty good all-purpose printer and there was not much problem to go from Windows XP to Windows 7 and Windows 8. After installing Windows 10 recently, I lost connectivity with the printer even after adding manually the printer previously used with old versions of Windows.

The LPT1 message points to rectifying the situation by enabling bi-directional support in the Properties dialog box.

Printer properties can be accessed as shown here. Right click the Printer icon and from the drop-down click on the sub-menu Printer properties which points to the printer and the fax device.

Click on the Printer to open the Properties window and move over to the ports. Herein you will find the check box.

You enable it and go back to try printing, you get the same message as previously. You come back and look at properties again. You will be surprised to see it is disabled. I tried couple of times and then realized that probably driver update is needed.

Bing found me the needed driver at this site:
http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_mx_series/pixma_mx432#DriversAndSoftware

Canon site is good as I could get the driver although the printer is old.  The site recognized the OS and all I needed to was to get the driver.

Download this (mp68-win-mx430-1_02-ejs.exe) to your computer (Toshiba Satellite S70 series) and double click to install. Make sure your printer is turned on and the printer is connected to the laptop with a USB cable.

Although you are configuring it for operating with Wi-Fi you still need to do this initially so that the printer gets the needed files.

During running the executable the program  recognizes the access point for Wi-Fi connection and on clicking Yes you get connected to the printer and you are ready to go.
