I'm seeing this in a hacked 3.0.23 kernel.  I don't
recall seeing this on 3.0.19 or earlier, but I wasn't looking
very hard either...

SOME POINTS ARE WHEN YOUR EPSON PRINTER NOT PRINTING:

1.First, you must close up your printer and concurrently unplug the ability source and USB cable in addition.
2.Wait for a long time, again plug-in the printer.
3.Now you wish to print a top-quality Diagnostic report on the Print test page.
4.You will find an option of the Printer’s display screen.
5.Either check your user’s printer user guide manual.
6.Check the quantity of ink available within the cartridge.
