I've got excatly the same problem with a HP PSC 1510 which however is absolutely recognized.
It's possible to print when it's directly connected to the PC.
On the other hand, when it's connected on the network using my LiveBox2 I get the message "cups-ipp-missing-validate-job" and "Print file was not accepted".
I'd like to indicate I'm not alone as this can show it
