epson banding & systems

["Gordon J. Holtslander" <holtsg@duke.usask.ca>]

Hi:

I did some very preliminary testing of printing with different systems and
drivers on my humble epson stylus photo 700 & PC.

I printed the same image file on the same printer in color on plain paper.
Its a low resolution scan saved as a jpg of a cyanotype intended for a web
page (120dpi)

I just wanted to see if there was a difference between prints made using
different systems and drivers on the same equipment.

>From windows I used the standard windows epson driver and got banding.
It looks like the printer consistently put too much ink at the same points
on each pass of the printer head. Printing the image with the paper in
portrait alignment the banding is vertical.  Printing with the paper in
landscape alignment produces horizontal banding.  The banda are along an
axis 90 degrees from the path of the printer head across the paper.

I printed from both photoshop and netscape.

Is this the typical kind of banding that people find with epsons?

Using linux and the CUPS driver for this printer I got an image with
absolutely no banding. The image is not as dense or as contrasty as the
windows image. I printed both in both landscape and portrait alignments
and used linux netscape and GIMP.  Again no banding what so ever.

I'm almost out of black ink, I'll try Keith Gerlings suggestions about
refilling and do this in black

I'll try scanning something at a much higher resolution and see what
results I get.
