(3) Borderless Printing
The image is printed on the entire paper surface, so that no margins are left on the four
sides of the paper.
The media types available for Borderless Printing are PR-101 and GP-301/GP-301N.
For all other media types, the print quality may decrease.
(4) Amount of Extension
When you select Borderless Printing, the sections that extend beyond the paper are
not printed because the image is enlarged to a size slightly larger than the paper size.
You can use the Amount of Extension slide bar to adjust how much the image
extends beyond the paper.
It is recommended that you normally set the slide bar to the right end.
If you move the slide bar to the left to reduce the extension amount, a border may
appear.
(5) Scale
Specify the scaling percentage to resize the document for printing.
(6) Orientation
Select landscape or portrait printing.
(7) Custom
To specify a custom paper size, click this button to open the Custom dialog box after
selecting Custom 1 to Custom 3 in the Paper Size popup menu. The Custom Dialog
Box allows you to specify the length and width of the paper.
(8) Utilities
Click to open the Printer Utility dialog box for maintenance operations such as print
head cleaning and nozzle check pattern printing, as well as for changing the print
mode.
