Dear community,
I post here in case my trouble is a famous one (I doubt because google didn't lead me anywhere).
Trying to print to a Sharp printer (AR-M256 or MX-C311), I keep receiving broken pipes. The server is under debian squeeze with official packages. The server and the printer are on the same network using an Ethernet Bridge VPN (openvpn). Ping echo is around 40 ms.
TCP dump show the printer keeps sending Dup Ack after a little time. Is it due to network ? To the printer card ? To the use of openvpn on an ADSL link ? Is their parameter to set to avoid that ? Is using PCL5 would change anything ?
Here is a dump of a job always hanging at 28 %. Regarding the CUPS test page sometime it manages to print it, sometime not.
