I have a Canon Pixma MX 510 and I am printing from a Windows 11 x64-based system. I have the latest driver installed (mp68-win-mx510-1_03-ea24.exe). When I print text and images (both in B&W) the images print fine but the text is uneven or blurred (like double vision). So in the same pptx document, I entered text but I also pasted the same text as an image. Again, the text was even but the image is fine (see attached photo). I tried both automatic and manual print head alignment but it didn't help. Any ideas on how to fix this? Thanks for your help.
