Canon PRO-100S unusable on Windows 11 — no drivers, no suppor

[antikvar99]

Dear Canon Support Team,

I am writing to formally express my dissatisfaction regarding the lack of driver support for my printer, the Canon PIXMA PRO-100S, on Windows 11 (version 25H2, 64-bit).

This printer was a significant and expensive purchase for me, and I chose Canon based on its reputation for reliability and long-term product support. However, after upgrading to a new computer running Windows 11, I discovered that there is no proper or fully functional driver available for this model.

As a result, I am currently unable to use the printer at all, despite it being in perfect working condition. This effectively renders the device unusable, which I find unacceptable—especially considering that modern operating systems like Windows 11 should be supported for professional-grade equipment.

I would like to request that Canon provide one of the following resolutions:

1. A compatible and fully functional driver for Windows 11 (64-bit);
2. Replacement of my printer with a currently supported equivalent model;
3. Or appropriate compensation/refund due to the loss of usability caused by the lack of software support.

Please note that I am prepared to escalate this matter further if no satisfactory solution is provided. I expect a clear response and resolution within a reasonable timeframe.

I look forward to your prompt reply.

Does this not work?

Dear Canon Support Team,

Thank you for your response and for providing the software link.

Unfortunately, the software you provided does not solve the problem. The printer is still not detected on my new computer running Windows 11 version 25H2 (64-bit), despite multiple installation attempts and troubleshooting efforts.

At the same time, the printer works correctly on my older computer with the previous version of Windows, which clearly confirms that the hardware itself is fully functional and that the issue is directly related to software and driver compatibility.

I also somehow managed to install a Japanese version of the software for this printer. It actually worked, and the printer was detected by the system. However, because the entire interface was in Japanese and extremely difficult to understand, I was forced to remove the software.

This further confirms that the issue is not with the printer hardware itself, but rather with the lack of properly functioning and accessible international software support for modern versions of Windows.

I would like to emphasize once again that the Canon PIXMA PRO-100S is a professional-grade printer and was a significant and expensive investment for me. It is extremely disappointing that such a device effectively becomes unusable simply because Canon no longer provides proper support for modern operating systems.

At this point, I am asking Canon to provide one of the following:

• A fully functional and officially supported driver for Windows 11 version 25H2 (64-bit);

• A confirmed technical solution that actually allows the printer to function correctly on modern systems;

• Or an alternative resolution, including replacement or compensation, considering that the printer itself remains fully operational but cannot be used due to the lack of software support.

Please understand that from a customer’s perspective, this situation is unacceptable for a premium professional product.

I would appreciate a clear and practical solution rather than another generic software link that does not resolve the issue.

I look forward to your response.

This is a user forum. 
Have you contacted Canon support?  The US number is 1-800-OK-CANON. 

I don’t think the 100S is a US model, so you would need to check for your country. It should be found on the website where you found the driver for your country.
