PIXMA PRO-100 Part of image is random lines from another part of the image

[gakersm]

I recently updated my ON1 software and Mac OS to Tahoe.  Now, prints on A3+ paper are printing perfectly for about 3/4 of the photo.  The other 1/4 is just some random lines from a portion of the photo (like the sky) repeated over and over again.  I have changed orientation and scale, even saved it as a PDF and printed that to rule out ON1, the end result is the same.  I updated the driver for Tahoe and ran all the maintenance functions.  I am connected via WiFi but that has never been an issue (for the past 8 years) and connecting via USB is not really a viable option.  I don't have any issue on smaller paper.  Does anyone have any other ideas?  I have wasted a lot of expensive paper and ink trying to figure this out!!

I was doing some printing today when I saw your posting.

MacBook Air M2 w/macOS Tahoe 26.1. Latest Pro-100 driver. Printer Wi-Fi connected. Wasn't printing borderless.

I do not have the problem you are experiencing, but I do have an issue getting poor colors when printing from Lightroom. When I print using Binartem Qimage One colors are true.

Do you have issues if you don't print borderless?

Hi John, thanks for the feedback.  I need to also reset my WiFi to rule that out, just haven't had time to be unconnected this morning.  When I do that, I'll try to print w/o borderless on and report back.  I think I saw that mentioned in some other threads I had seen around the internet too.

After resetting the WiFi and switching off borderless printing, I am getting the same results.  I also failed to mention earlier that I tried printing two different photos on A3+ and the same thing happens to both.  It is clearly something with the printer and not photo software related.

Agree. I haven't tried using Canon Print Studio Pro, but I was along time user of Qimage Ultimate on my PC so tried Qimage One on the Mac and am happy with it. I think they have a free trial if you are interested.
