acceso denegado a impresora compartida por samba

[josep]

Tengo una impresora Epson instalada en linux que funciona con el driver de cups. Localmente un usuario puede imprimir con el comando lpr. Pero si un cliente windows intenta imprimir no pasa nada, i al acceder a la impressora compartida me contesta:   acceso denegado, no se pudo establecer conexion   Este es mi smb.conf:   [global]  passwd program = /usr/bin/passwd %u  auto services = homes  dns proxy = no  encrypt passwords = yes  socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=4096 SO_RCVBUF=4096  invalid users = root  max log size = 1000  obey pam restrictions = yes  passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n  workgroup = xacal  server string = %h server (Samba %v)  syslog = 0  log file = /var/log/samba/log.%m  load printers = yes  os level = 20  printcap = cups  load printers = yes  printcap name = lpstat  printing = cups   [homes]   [recursos]  path = /mnt/recursos  create mode = 664  writeable = yes  directory mode = 775  force group = xacal  comment = Recursos compartits  wide links = no  force user = xacal   [www]  path = /var/www  writeable = yes  create mode = 664  directory mode = 775  force group = xacal  comment = webs a iskra  force user = xacal   [epson]  path = /var/spool/samba  writable = no  create mode = 0700  lprm command = cancel %p-%j  lpq command = lpstat -o %p  comment = epson a iskra  guest ok = yes  print command = lpr -P %p -o raw %s -r  printable = yes
