#761 Canon MP230 higherst quality mode not working properly
I have Canon MP230 on my hands and use it a lot on daily basis, but I can't properly print the photos with highest print quality (without Windows being involved), that is achieved via setting the paper to Pro Platinum Photopaper (Photo Paper Pro Platinum), and resolution to 1200x1200 DPI PHOTO HIGHEST proPlat (that is should be available and used only when Pro Platinum Photopaper is selected, and it is in Windows's Canon driver; see the screenshot of what params are used that didn't work at all and see the symptoms below).
The "symptoms": printer gets the job, takes a paper, tries to begin to print, move the head to paper and just sits there, does nothing, no head movements or something after that, then after some time (it process the print job and probably rejects it) - spits out the paper (ends the print) - so nothing is printed on paper
I have little if none knowledge of how exactly Gutenprint works under hood, but I was able to capture the current job files from Linux, and proper job from Windows, see the attachments
The used parameters for Linux is:
lp -d MP230_capture -o Resolution=1200x1200dpi -o MediaType=PhotoProPlat Downloads/print-color-test-page-cmyk-1.pdf
lp -d MP230_capture -o Resolution=1200x600dpi -o MediaType=Plain Downloads/print-color-test-page-cmyk-1.pdf
lp -d MP230_capture -o Resolution=1200x600dpi -o MediaType=PhotoProPlat Downloads/print-color-test-page-cmyk-1.pdf
lp -d MP230_capture -o Resolution=600dpi -o MediaType=Plain Downloads/print-color-test-page-cmyk-1.pdf
Used parameters on Windows is attached as screenshots
The PDF is attached also - it's from https://colortest.page/cmyk-color-test-page/
At the time of this investigation "why it doesn't work", Claude concluded it's because of mode set that was probably ported from higher class printer (1200x1200dpi_photohigh2) - I can't be sure because I don't know how to properly compare those captures of print jobs, but at least the 600 DPI HIGH mode in Gutenprint is equal to Plain paper High in Windows since they both surely uses Fine nozzles (I have dead regular Magenta nozzles and working Magenta Fine, so that's how I can test out if it is, plus the behavior is almost if not the same). I can try to capture the Gutenprint logs in debug mode again and attach them if that would help
I can provide more captures from Windows print jobs with different settings and make remote access to the Windows machine that controls my MP230 if that will help in development
If would be helpful - I can provide the printer's FW version and other info via resetter tool
I already made an older ticket there, but it lacks a lot of details: https://sourceforge.net/p/gimp-print/support-requests/619/
