The “Print Size” dialog
The output resolution determines the number of pixels used per unit
length for the printed image. Do not confuse the output resolution
with the printer resolution, which is expressed in dpi (dots per
inch); several dots are used to print a pixel.
When the dialog is displayed, the resolution shown in the boxes is the
resolution of the original image. If you increase the output
resolution, the printed page will be smaller, since more pixels are
used per unit of length. Conversely, and for the same reason,
resizing the image modifies the resolution.
Increasing the resolution results in increasing the sharpness of the
printed page. This is quite different from simply reducing the image
size by scaling it, since no pixels (and no image information) are
You can set the printing Width and Height by using the
text boxes. You can also choose the units for these values
from the dropdown list.
As soon as you change the Width or the Height, the X and/or
Y resolution values automatically change accordingly. If the
two resolution values remain linked, the relationship of the
width to the height of the image is also automatically
maintained. If you would like to set these values independently
of each other, simply click on the chain symbol to break the
X resolution; Y resolution
You can set the resolution used to calculate the printed
width and height from the physical size of the image, that is,
the number of pixels in it.
Use the text boxes to change these resolution values.
They can be linked to keep their relationship constant. The
closed chain symbol between the two boxes indicates that the
values are linked together. If you break the link by clicking
on the chain symbol, you will be able to set the values
independently of each other.
