Chapter 6 Development Information for Customer Displays Programming Guide (XML Print Service) This section explains the programing methods for application development with ePOS-Print XML. Since the end point addresses of the TM printer and the customer display are different, printing with the TM printer and accessing the customer display cannot be carried out for the same document. How to Use XML Schemas In XML schemas, the configuration method is the same; only the TM printer files and file names are different. See the How to Use XML Schemas (p.41), change the file name and configure the settings. ❏ XML schema file for TM printer epos-print-x.x.x.xsd ❏ XML Schema file for customer display epos-display-x.x.x.xsd Creating and Sending the Documents to be Displayed Create a print document using elements in the epos-print root element. For details on elements, refer to XML for Controlling Customer Display (p.116). Send the document you created with the XMLHttpRequest object.

Chapter 6
Development Information for Customer Displays
Programming Guide (XML Print Service)
This section explains the programing methods for application development with ePOS-Print XML.
How to Use XML Schemas
In XML schemas, the configuration method is the same; only the TM printer files and file names are different.
See the
How to Use XML Schemas (p.41)
, change the file name and configure the settings.
XML schema file for TM printer
epos-print-x.x.x.xsd
XML Schema file for customer display
epos-display-x.x.x.xsd
Creating and Sending the Documents to be Displayed
Create a print document using elements in the epos-print root element. For details on elements, refer to
XML for
Controlling Customer Display (p.116)
.
Send the document you created with the XMLHttpRequest object.
Use the constructor to create an XMLHttpRequest object, specify the end point address of the customer display
to be shown in the send method, specify the document to be displayed and send it.
For details on the end point address of the customer display, see
Customer Display End Point Address (p.223)
.
Since the end point addresses of the TM printer and the customer display are different, printing with the TM
printer and accessing the customer display cannot be carried out for the same document.
