SOFTWARE SPECIFICATIONS
Corresponding Protocol TCP/IP
Network Layer ARP, RARP, IP, ICMP
Session Layer TCP, UDP
Application Layer LPD, FTP, TELNET, BOOTP, DHCP
NOTE: Print data can be sent by LPR and FTP of TCP/IP and dedicated socket protocol. Printer status is obtainable by
dedicated socket protocol.
NOTE: In the TCP/IP protocol environment, LPD and FTP are provided for printing; TELNET for variable setup; ARP, RARP,
and BOOTP/DHCP for address setup.
LPD protocol complies with RFC1179 and handles the list of logical printer name as queue name such as lp, sjis, euc. In
addition, a banner page can be printed by a proper setup.
When sending the job by LPR, the transmission order of data file/control file within the job will not affect print operation. In
addition, if the banner page is specified, it will be added to each data file. Job deletion by LPR is not available.
FTP protocol complies with RFC959 and handles the list of logical printer name as a transfer directory. File transfer to this
directory executes print operation. It is possible to specify ASCII(A), Binary(I) and TENEX(L8) as transfer mode - although the
mode difference is dependent on the client. A banner page may be printed with a proper setup.
TELNET Complies with RFC854. This operation consists of interactive menu form and enables change and reference of
internal setup, and to display status. To change the setup, enter “root” user and password at the time of login. Default of root
password is set as null (linefeed only).
