# 11.9. Printing to a SMB (MicroSoft) Printer

Microsoft use the SMB (Simple Message Block) protocol to transfer files and print jobs to hosts and printers. SMB can be used over TCP/IP, NetBEUI, IPX, and other lower level network protocols.

Unfortunately, most printers do not provide detailed status or error reports when using the SMB protocol. There are a very large number of printers that have deficient SMB support that causes problems when used in a high traffic or high throughput environment.

It is highly recommended that this protocol not be used unless there is no alternative.

If you have a printer or a remote print spooler that supports SMB You can use the SAMBA smbclient program to send a print job to an SMB client. The following is a sample Shell Script script which you can use:

        #!/bin/sh -x
        # This script is an input filter for printing on a unix machine. It
        # uses the smbclient program to print the file to the specified smb-based
        # server and service.
        # The 'smb' printcap entry below shows how to configure LPRng
        # for printing
        #
        # smb:
        #  :lp=|/usr/local/samba/smbprint
        #  :sd=/var/spool/smb:
        #  :filter= ... filter ...
        #
        # The /var/spool/smb/.config file should contain:
        #   server="PC_SERVER"
        #   service="PR_SHARENAME"
        #   password="PASSWORD"
        #
        # Set PC_SERVER to the server, PR_SHARENAME to the printer,
        # and PASSWORD to the password for this service.
        #
        # E.g.
        #   server=PAULS_PC
        #   service=CJET_371
        #   password=""
        #
        #
        config_file=.config
        if [ -f $config_file ] ; then
            eval `/bin/cat $config_file`
        fi
        #
        # NOTE You may wish to add the line `echo translate'
        # if you want automatic
        # CR/LF translation when printing.
        (
        #   echo translate
            echo "print -"
            /bin/cat
        ) | /usr/local/bin/smbclient "\\\\$server\\$service" \
           "$password" -U "$server" -N -P 1>&2

If the above script was in `/usr/local/libexec/filters/smbprint`, the printcap entry for this printer would be:

        pauls_pc:
          :sd=/var/spool/lpd/%P
          # we filter the output
          :lp=|/usr/local/libexec/filters/smbprint
          # you can add filters if you want to do specific actions
          :ifhp=model=hp4
          :filter=/usr/local/libexec/filters/ifhp
