How to use polarizing filters to reduce haze and deepen blue skies, by Gordon Laing, Editor of http://www.dslrtips.com
On printers that were badly blocked I have repeated this process several times before I was successful. I have heard that many people have used window cleaning solution to clear there blocked heads. Remember you do this process at your own risk, if this process goes wrong your Epson warranty will not cover the repairs of your printer.
Most Epson A4 printers allow you to customise the page size to much longer than the standard size. The width is limited to a maximum of 210mm, but the length can be up to 3 meters.
| Resolution | Print size at 300dpi | Print size at 150dpi |
| 6 megapixels | 10×6.5inches | 20x13inches |
| 10 megapixels | 13×8.5inches | 26×17 inches |
| 12 megapixels | 14×9.5 inches | 28 x 19 inches |
A 300dpi image from 6 megapixels camera is only designed to print at a size of A4. The printing of a larger picture at high quality is possible by printing at a lower resolution, this is subject to the fact that the cameras produced a good quality image. Most image from digital cameras using a low ISO will be of high quality.
