OP 270 and printer

Hello,

I have connected a printer Epson 6540 with a OP 270, with the USB port.
I have changed the properties of the printer.

Printer properties :

Printer language : PCL Inkjet
Port :USB1:
Network :-

Itworks in first time printing, but after that's I can't printing anymore, I checked again of the properties and their are thesame.

The errormessage is "Time out onprinter 6540 on port USB 1"


Best regards
