Question

Printer dialog box forces 180 ppi to 72 ppi

Hi All,

 

I hope that all of you are well.

 

Here is my problem. I have created an image in Photoshop 21.1 at 180 ppi. When I tried to print it in PS 21.1.1,  I first got to a screen that said "There was an error opening your printer. printing functions will not be available until you have selected a printer and reopened any documents." I then reopened file in a new session and hovered my arrow above File>Print. This "reset" the print settings and opened the Print Dialog Box. Since all the settings had been "reset" I had to select the printer, color management & etc to my preferred settings. The Print Resolution shows up as 72 ppi NOT the 180 ppi in my file. I therefore am unable to properly print the portion of the image that I want.

 

Below is a screen shot showing the "reset" printer dialog box before I made the changes to my preferred settings.

Any ideas? Is it the change up to PS 21.1.1 or ???

 

FYI - I use Mac OS Catalina 10.15.2, Canon Pro 100 printer and now PS 21.1.1.

 

FYI again - I upgraded to PS 21.1.1 and it solved the Dark Blue "Bleed" issue that was discussed in this link. The question there was is it a printer profile issue or a PS issue. My workaround was to use another Mac using High Sierra as a print driver.  It was a PS issue and it appears that  21.1.1 was a solution for the "bleeding" colors but did it create a new issue with the forced push to 72 ppi?

 

Stay Well and Thank You,

Jim

On Windows 10 Photoshop 21.1.1 set my canon 1D2 8MP Camera image  resolution to 389 PPI for a 6" x 9" portrait on my Canon Pixma Pro-10. What does menu Image Size show for the size and resolution of your document?

Hi JJ,

Here is a screen shot showing the size and resolution of my image.

As you can see the printed size of this image is 99 x 76 1/2 inches and the resolution is 180 ppi. It is quite large so it takes 81 - 8 1/2 x 11 inch prints.  In the previous screen shot from the print dialog box the image size changes to 247.5 x 191.291 inches which is incorrect.

Any other suggestions or questions?

Jim

Anytime you resample you loose some image quality you either throw away detail you have for an image or make up details you don't have for the image.  If you are painter create the image the size and resolution you need for the print.  If you use a camera use one that captures a good number if pixels the will work well for the largest size print want with high resolution.   Huge prints do not need to be printed with high resolution pixels.  The image will not be viewed from a distance where the human eye can resolve down to see its high resolution.  Larger pixels can be used the image will look fine. You will not be able to see a 1/180" x 1/180" pixel from six feet away. Do you think those electronics billboards you see on the highway are display giga pixels images,  or you 60" 4K TV is displaying  more than 8.20MP pixels. 3840x2160 is 8.2MP

 

That is ‭245,434,860‬ pixels where did they come from did you stitch thousands of images?  No they are made from resampling far fewer pixels. You are not going to view your 99" print from 1' away. You do not need that many pixels for a print that size.


I have been printing images this size,  99 x 76 1/2 at 180 ppi, for over 4 years. I like the quality that I can see from both up close and back 10 feet.

Again what I really need to solve is WHY does 21.1.1 force me to reset my dialog box?

 

Here is something odd. I can print older images from PS 21.1 and the warning, "There was an error opening your printer. printing functions will not be available until you have selected a printer and reopened any documents." does not appear. Is there something embedded in 21.1.1 files that is causing this warning?

 

It seems as if this is an issue with PS 21.1.1 using MacOS Catalina.
