Trouble printing photos (on a Mac)

Trouble printing photos (on a Mac)
Hi, sorry if this is very basic but my Google searches have not been successful. I am using Gimp on a Mac Pro with all the latest software, and am printing to a Canon printer using 4"x6" photo paper. I've tried printing both borderless and with borders.

I have some photos that I did some light retouching to. No cropping or size adjustments, just filters and stuff. When I try to print, a small percent of the photo is cropped off. This isn't seen on the "print preview" screen. It looks normal there. So for example if there's a picture of a football field that fills the entire shot, the 5 yard line on either side isn't on the printed version.

If I save as PDF, the entire photo is there. If I export the photo to JPG, the entire photo is there. It's only when I print from Gimp. It's also the case that if I export (to pdf or JPG) and print using Preview, the entire photo is there.

Now, one additional problem is that Preview is printing the photo wrong. The colors are off. It's darker. This is true even if I use untouched photos. It's true if I select the Canon color profile, or ColorSmart. It's true if I print at "best" or "normal". Gimp however prints the colors true. It also does not use the system print dialog, so it doesn't have all the options.

Ideally, I would either be able to print from Gimp without losing ~5% of my photo, or from Preview without the very mysterious color change.

If anyone has any ideas as to either of these issues I would be grateful. Thanks!

K, Update: Try checking the color settings of your printer in the printer properties to make sure its configured correctly.

Then in gimp, with the image you want to print go to:
Image > Mode...

... is it set to RGB by default?

Check out this thread for conversion of DPI & image print size:
http://gimpforums.com/thread-dpi-alterin...g-purposes
-There is an equation to figure it out there.

Check Gimps print settings (PAGE LAYOUT):
File > Page Setup...
-next to size: click "4x6"
-Pick your printer source: If not known/unsure, leave at "Automatically select" or let us know what the options are.
-Chooser your image orientation (is it wide or tall) then pick appropriately, portrait(tall) or landscape(wide)

Last check gimps print... settings
File > Print...
Check the settings you get there & post a screenshot of what it looks like, then I can advise further.

Good luck!

RE: Trouble printing photos (on a Mac)
Thanks for your reply.

I'm not sure how to check my printer's color settings. In the control panel there is no option for such a thing. However, you can select color settings while printing.

In Gimp image mode, it is set to RBG.

The thread you linked was more about proper DPI and didn't have anything relevant to my issue.

In Gimp, the page size is set to 4x6 borderless, although I get the same issue with borders.

In the print dialog, the image settings are:

width 5.333
height 4.000
x and y resolution 864.000
position
left right 0.333
top bottom 0.000
center both

I'm afk until saturday but sometimes I like to sneak a peak at the forums if I have the time xD your in luck today.

In your case, the proper DPI is important, thread linked, more or less.

Something is off about your X Y resolution (DPI) & your width & height are set to 5x4

A document with the Image size of 6 x 4 (or w: 6.400 by H: 4.000) = X Y resolution of 100.000

-In the print "Image Settings" of Gimp, change the height to 4.000.
- Then make sure Center is on "Both"
-You could try []Ignore Page Margins

If your image is being cropped, it means that it is too big for the page size.

One other thing, I did a new image at resolution(scale) of 640 x 480 px.
When I went into "Print > Image Settings" and set the X Y resolution to 864.000, the image size was lest than 1 inch!

*What resolution is the image? (800 x 600, 320 x 200, etc....) (see title in image window of my example)

Also, please include a screenshot of your "Image Settings" Page like the on below in your next reply to help out a little more.
"New Reply" scroll down to "Attachments" Click "choose file" then "add attachment" > Post Reply
   

& if I don't reply soon I'll get back to you on Saturday ^_^

P.S.

Is the color setting you found the same as discribed here? Instructions per your macOS version.
