Epson PRO Reference Manual page 52

The printer prints blank pages.
Make sure EPSON Stylus Pro or Pro XL is selected as the
default Windows printer driver (PC driver) or is the last printer
selected in the Chooser (Macintosh driver).
Make sure you selected the correct Paper Size option in the
printer driver; see your Setup and Software Guide for
instructions. Also make sure the margins you selected in your
application software fit the paper size you're using.
Verify that the ink cartridges are not empty by running a
self test.
Text printing is slow.
You may be using printer driver settings that are more suitable
for graphics printing and unnecessarily slowing down text
printing. To speed up text printing only, turn off MicroWeave
mode and turn on High Speed mode. Some combinations of
Printing Mode (resolution) and Media Type do not allow you
to select these settings; if this is the case for your settings, select
a lower resolution, possibly using 180 dpi for drafts and
360 dpi for your final output. However, do not turn off
MicroWeave when printing final copies of high-quality
graphics or photographs.
Ink cartridges do not last as long as expected.
The ink cartridge life depends on the amount of ink used in
printing. If you often print pages with large graphics and dense
text, you will use up cartridges faster than if you print pages
with less ink coverage. Cleaning the print heads more often
than necessary also consumes ink.
