Very Computer

I have this strange problem with Epson Stylus Pro XL+ and CUPS:
whenever I print a page, the printer prints the page correctly, and
then prints an almost empty page with only the last line of the
previous page, but that line is already printed in the first page.
If I print a multiple page document the printer just print such an empty
page after every page correctly printed.
I've already tried changing setting, margins, page dimensions, etc.
I have this problem since I updated the CUPS of Mandrake 9.1 to
the last version with MandrakeUpdate. It was a security update so I
couldn't avoid it.
Thanks for any help.
