Borderless prints can be hard to make.
To avoid problems, do the following.
1) Make sure your printer can make borderless prints.
The manufacturer may state their printer does borderless, when it only prints close to the edge.
Check photography forums for the experiences of other users of your printer.
2) Make sure the paper size you're using is capable of being printed borderless.
3) Examine the page setup section to see if you need to designate the:
• Paper type.
• Method of loading into the printer.
For example, you may see:
Lumiére Letter (Sheet Feeder)
Lumiére Letter (Sheet Feeder - Borderless)
4) Peruse the printer settings section to see if you need to select borderless printing.
Look in every nook and granny.
There may be an obvious borderless selection.
Or, perhaps a discrete box called Border that has to be set to None.
Your printer doesn't have precise paper handling.
If the paper "misfeeds" by 1/100th of an inch, you won't get a borderless print.
Some paper types may feed more precisely than others.
Feeding accuracy may vary according to the amount of paper in the feed tray.
5) To compensate for the above, set the expansion or overspray feature.
The printer will enlarge the photograph slightly to spray ink beyond the edges of the paper.
You've set the printer above.
Now you have to set the editing software.
The two have to work together.
If they're in conflict, your prints won't be borderless.
6) Move the borders or margins to zero.
7) Some programs may also have settings for the image area.
Lightroom, for example, calls the area containing the image the cell.
8) If you still have borders, the aspect ratio of the photograph and the paper may be mismatched.
If so, look for a zoom-to-fill or zoom-to-fit feature.
You may also have to use a rotate-to-fit feature.
The image will enlarge to fill the paper.
It will be cropped, of course.
For example, digital SLR photographs have the same aspect ratio as 8 x 12 inch paper (3:2).
The digital SLR photograph aspect ratio doesn't match 5 x 7, 8 x 10, 8.5 x 11, and other paper sizes.
In the future, frame scenes in your viewfinder with later cropping in mind.
For example, if you're photographing actors for headshots, include extra space above and below the face for later cropping on 8 x 10 inch paper.
