iii) Printing the Image
PiezographyBW actually prints at 2160dpi and likes to have as much
image data in the form of pixels as it is possible to get. When using PiezographyBW
it is better to keep the image resolution as high as
possible without upsampling. Most of my images were printed with Photoshop
set for anywhere between 240 and 360ppi. Precise values do not seem to be
important so size the print according to your needs and if the Photoshop
output resolution falls above 240ppi, great. If it's less then make the
print smaller, do not upsample if you want to retain all the qualities of PiezographyBW.
Making a print in PiezographyBW is slightly different to the normal
process of selecting Print from the Photoshop File menu. With PiezographyBW
you actually print via the Export command, again found under
the Photoshop File menu.
The "Gamma" and "Dot Density" options are designed
to allow the user the opportunity to fine tune the printer output. The
user manual explains both in detail, so I'll give them a miss. Nevertheless,
I never found any need to use either them.
Setting up the printer is also fully explained in the user manual.
However, you should notice the option for Page Setup in the PiezographyBW dialog shown below. The option will give you access to the standard Epson
driver from where you will choose the media type, printer resolution
(ideally 1440dpi) and paper size. The other settings are all pretty much
irrelevant; PiezographyBW does its own thing.

Choosing the correct media profile is important. Each paper type listed
has been profiled to achieve the best possible output. If you find
yourself testing a paper that is not listed, try the
"Unsupported" option. However, you'll probably have to create a
new dot gain curve for previewing the image. Some users have reported that
using the "Unsupported" option produces very good results with
many of the Epson papers. I haven't tried this for myself but do keep it
mind for future reference.

One thing that becomes very apparent with PiezographyBW is the speed of
printing, it is much quicker than the standard Epson driver.
