connect method

Syntax

connect(ipAddress, port, callback);

connect(ipAddress, port, callback, options);

Parameter

connect("192.168.192.168", "8008", callback, {"eposprint" : true});

Supplementary explanation

• For the syntax to specify the options, refer to Epson ePOS SDK for JavaScript User's Manual.
• This API will succeed regardless of the connection status of the TM printer (master) and peripheral devices.
• For continuous processing, or for controlling the printer from a single terminal, it is recommended to keep the application connected with the devices.
• If the options parameter is omitted, "false: disabled" will be specified.
• When connection has failed while the ePOS-Print option is not enabled, enable the ePOS-Print option and make the connection.
  When this connection is successful, "OK" is passed to the callback parameter regardless of the communication method specified in the port parameter.
• When the eposprint option is enabled by specifying 8043 in the port parameter and true in the options parameter, "OK" is returned to the callback parameter.
• When the eposprint option is enabled by specifying true in the options parameter, the methods that can be used in the ePOSDevice object are as follows.

• When using the Automatic certificate update feature, set the host name to the ipAddress.
  The host name should be the product serial number hashed with SHA-256 and encoded with Base32, plus ".omnilinkcert.epson.biz" at the end of the string.
  See the "connectHostName" method in the sample program "printer_sample.html" for an example of a program to generate a host name.
  Select "8043" as the port.
  The Automatic certificate update feature is only supported by some TM printers. To find out if this function is available for the TM printer you are using, refer to the "Application Development Information" chapter of the Technical Reference Guide for that TM printer.
