Printing just stop, as if timeout occurs. The same happen when I try to print on local printer, or on SMB printer, or on LPD printer. I have tried to configure Samba, Cupsd, and nothing was helpful. smb.conf: socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=8192 SO_SNDBUF=8192 cupsd.conf: KeepAlive On KeepAliveTimeout 600000 MaxClients 1000 MaxRequestSize 1000000000 Timeout 30000000 ReloadTimeout 18000 Also, on Windows machine, after about 15 minutes I get an error "Error - printing" for that document. On some dot-matrix printer this occurs after longer period then 15 minutes.
