IEEE1284 PARALLEL INTERFACE
The parallel interface is a plug-in module that can be installed by the user and conforms to IEEE1284
specifications. It automatically detects the IEEE1284 signals and operates in the high speed mode. If the
IEEE1284 signals are not detected, it will operate in the slower standard Centronics mode. For this reason, an
interface cable and host interface conforming to the IEEE1284 specification must be present to fully utilize the
speed capabilities. This interface also operates bi-directionally and can report the status of the printer back to the
host.

UNIVERSAL SERIAL BUS (USB)
The Universal Serial Bus (USB) interface is a Plug-In Interface Module that can be installed by the user. It requires
a driver (shipped with each printer that has the interface installed) that must be loaded onto the PC and configured
to support USB peripherals using Windows 2000 or above. Details for loading the USB driver are contained in the
USB Interface Manual that is shipped with each printer with a USB Optional interface installed. Up to 127 devices
may be connected to a USB port using powered hubs.
BLUETOOTH
The Bluetooth interface on the CT4i printer complies with the Bluetooth 1.1 Class 2 standard. The Bluetooth
interface and the printer are connected by a serial interface at a transfer rate of 115200bps.
ATTENTION: This Interface Type Is Not Compatible With Windows 98 Or Windows Me.

LOCAL AREA NETWORK (LAN) ETHERNET
A Local Area Network (LAN) interface is an optional Plug-In Interface Module that can be installed by the user. It
requires a driver shipped with each printer that has the interface installed. The driver that must be loaded onto the
host computer and configured to run one of the supported network protocols using a 10Base-T or 100Base-TX
LAN connection. Details for loading the LAN driver are contained in the LAN Interface Manual that is shipped with
each printer with a LAN Optional interface installed.
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).
