Printing Problem

[CosmiCat]

Hello everybody
I'm unable to print my documents with TXZ Pup

printer : Epson Stylus Photo R300
installed:
- cups-1.4.4-i486-7_SLXR
- gutenprint-5.2.4-1.4.4-i486-3_SLXR
- ghostscript-8.63-1.4.4-i486-4_SLXR

If I try to print the test page, I get this message:
Unable to print test page:
 Unsupported format 'application/vnd.cups-banner'!

Every document I try to print appears in the jobs list but the state column report : canceled at...
With others Puppy derivatives (for example Dpup) I have no problems.

Thanks in advance.
