Thank you for your detailed report, Matteo.
Please enable debug logging on the server and obtain an error_log for a
job to post here. The printing section of the wiki should help you with
this.
Would you also run the command (as root is less hassle):
cupsfilter -p /etc/cups/ppd/Epson_2530.ppd -m printer/foo -e /etc/nsswitch.conf > file.out 2> wf2530.log
and post wf2530.log. Check that file.out exists and is identified as
"data".
Regards,
Brian.
