Setting the Trimming
Image area to be printed
Depending on the printer, the trimmed image area might not be printed
as you specified.
The smaller you make the trimming frame, the grainier the picture will
look. If the picture will be too grainy, the trimming frame will turn red.
When trimming the image, look at the camera's LCD monitor. If you look
at the image on a TV screen, the trimming frame might not be displayed
accurately.
The trimming frame shape will be different depending on the [Paper
settings], [Image] / [Paper], [Page layout] / [Borders] settings.
