Weird Picasa bug (only affects Lexmark printers?)

If you open and then save the JPEG in Paint (overwriting the original file) the problem goes away. that doesn't mean it's a bug in picasa. if the jpeg from picasa is valid, then it's word and/or lexmark. But they behave fine with picasa files that havn't been compressed by Picasa export. So I think there is something wrong in the file header which either the Word print engine or the Lexmark is getting confused about. And the fact that just importing the file into Paint and saving it again clears the fault points to something in the JPEG. different doesn't mean one is wrong. can you post a sample jpeg exported from each app? Well I could, but as far as I am concerned I have a fix. I can certainly do that if anyone confirms they would like to do some investigation. I was partly posting this in case anyone already knew about it, or so that someone Googling the same problem in the future would find it. you don't have a fix. you have a workaround that avoids the issue. the content of the photos is completely irrelevant, as long as the sizing issue can be duplicated. take a photo of something random, or even fill it with black. no need to share internal photos if you don't want to. Happy to share something. With a solid black image I wouldn't be able to see that the process had failed. then post real images. the point is they the images do not need to be anything internal to your company or you personally. all that matters is that the issue you describe can be duplicated. two solid black images would still be sized differently. without examining the files, it sounds like the resolution tag, which is sometimes used for initial image sizing/placement in some apps, is set differently. Yes, that was one of my guesses but I am not all that familiar with this stuff. then post samples so that those who are can investigate. if that's the case, there is probably a default setting which can be changed. Yes but what setting? default resolution, which is usually ignored, except by some apps. In Word, you check page layout via print preview. word is probably working as designed. however, that you get different results with lexmark suggests an issue with lexmark. And you expect the printer to give you the same thing (although occasionally a line of text spills on to the next page). that's not good either. how did you validate the jpeg? or did you? I don't know how to. that would be a no. Indeed. Suggestions would be useful. The export files look fine in several different viewers. that means nothing. what does exiftool show for tags, notably resolution? |

The printer dialogue should be specific to the Lexmark, and there is probably a setting in there that you are overlooking. If you see the same printer dialogue for all your printers, you need to find the correct drivers for the Lexmark and install them. Drivers was the first think I looked at. I'm just printing a word file. The print preview is fine. The lexmark output fails, other printers are OK. Did you download and install the latest printers from the Lexmark site? Did you dig through all of the advanced options in the printer dialogue? I have no idea if this is the issue, but since this is specific to only the Lexmark printer, it seems to be the most likely cause. Another option might be to resize the jpg and save to a new file before printing. That's what I am doing. I was using Picasa to do the resize because that's what I use for cropping and straightening (and maybe occasionally a tweak on fill, contrast, or colour). My point is that the resized picasa file fails to print *to one specific printer* when put into the word document. But if I import the file into paint and re-save it before the insert then everything is fine. |

Agreed, but it's not difficult to tweak the word file to fix that. I'd always thought it might be something subtle to do with the printable area. I've seen this with several different applications. how did you validate the jpeg? or did you? I don't know how to. that would be a no. Indeed. Suggestions would be useful. The export files look fine in several different viewers. that means nothing. It means that *if* the problem is in the EXIF data, it is a subtle one. what does exiftool show for tags, notably resolution? Had a look at that, but ATM it's not unzipping to an .EXE for me. I will have another go. I think I used to use it in XP or W7 days, but W10 brings a whole load of new problems with all sorts of stuff. Don't disagree with your implied point that if application B gets confused by code produced by application A, then is not immediately obvious which application is at fault, or even if it is meaningful to assign "fault". In this case, I can't change the way the Lexmark interprets the Word file, but I have an easy fix by modifying the Picasa file that I inserted into Word. So it feels *to me* like the Picasa file is "wrong". |
