cups-pdf make only Test_Page.pdf when printing from client

[froggy]

ihave installed cups with cups-lpd enabled and cups-pdf on unbuntu server

when i do a "ls|lp -d pdf" on the linux box i get a nice pdf file
but when i do "ls|lp -d pdf" on a client that connect to linux server pdf spool, i obtain a Test_Page.pdf
It's a sort of banner page with this
