It is Canon. It is my wife who will use the printer and she does not "do" computers! I quite understand the answer if there is a way, when returned to memory card only, to choose Portrait or Landscape but I can't see that at the moment so cannot test the result.
Sorry to be unclear! I simply meant that whatever tinkering I do with the printer if it is attached to my computer, it will end up being used Memory Card only by my wife. The card itself is unchanged. If the printer, when not attached to a computer, is unable to be programmed to change settings such as Portrait and Landscape that is not good news. However without that I can't see how we can prove either way that this is the reason why part of the printed photo is cut off.
Question of aspect ratio is beyond me I am afraid. Does the Canon printer have a setting to change from Portrait to Landscape? Whichever mode it would, I would guess, have been the same as on my computer which looks like landscape and where it has printed ok.
I am having to leave this for an hour. Is it any help to you to see a scan of the photos and therefore does this system accept attachments?
Back again. It would seem so simple to decide on the aspect but as the object is a round plate that becomes less obvious. However I am sure that it is landscape.
I don't think my previous message will have got to you. I have now tried something else which has had a disappointing result. When I printed the picture from the memory card through my computer it was fine. I have now printed it directly from the memory card through that printer a Canon MG5450 and it has printed with the same fault as with Canon 4250 i.e. bits cut off the side. That to me would indicate that there is an embedded problem with the Canon printers when printing from a memory card.
Well perhaps becoming clearer if not more helpful. Printing a regular jpg from the memory card via the printer loses some small amount of the picture on both sides in landscape. The same jpg printed via the computer using Windows Photo Viewer with "Fit to frame" checked produces an identical print. The same jpg printed with "Fit to frame" unchecked produces an accurate print albeit by definition not fully filling a 6 x 4.
This seems to me to suggest that the printers are set by default with "Fit to frame" checked. So now I suppose the question is does a Canon printer allow the user to uncheck the default "Fit to frame"?
Thanks for your endless patience. Whilst some or even most of what has been discovered is not exactly helpful I have always thought that in the end better to know than not know! I will look at the Borderless setting. I have a feeling that it may be set to "borderless" so maybe I will change that and see if like "Fit to frame" it has any effect.
Am signing off now although if a shriek of success reaches you I would be surprised!
Thanks again. Anthony
