Abstract

An XML processing system for use in a barcode printer apparatus includes a computer system operatively coupled to the barcode printer apparatus. The computer system further includes an XML processor configured to receive, parse, and process an XML input data stream and obtain schema identified in the XML data stream from a schema repository. The XML processor validates the XML data stream based upon the schema obtained. Also included is an XSLT processor configured to obtain a stylesheet identified in the XML data stream from a stylesheet repository. The XSLT processor transforms data in the XML input data stream into transformed XML data based upon the stylesheet obtained. Also, an XSLFO processor formats the transformed XML data into formatted XML data based upon XSLFO instructions contained in the stylesheet. A barcode rendering subsystem then receives the formatted XML data and generates a bit map representative of the bar code label. Alternatively, the system includes a SAX processor configured to receive and process the XML input data stream, a ZPL processor configured to receive and process a format template, a variable data integrator configured to develop an association between the XML data contained in the XML input data stream and the format template, a formatting engine configured to format the associated XML data according to a format governed by the format template, and a barcode rendering engine configured to receive the associated and formatted XML data and generate a bit map representative of the bar code label.

Claims

1. An XML printer system adapted to print bar code labels based upon an extensible markup language (XML) input data stream and a format template, the printer system including a printer apparatus having a media control system, a print head assembly, and a print head driver, the printer system comprising:

a computer system operatively coupled to the printer apparatus;

the computer system further including a memory subsystem;

a SAX processor configured to receive and process the XML input data stream;

a ZPL processor configured to receive and process the format template;

a variable data integrator configured to develop an association between the XML data contained in the XML input data stream and the format template;

a formatting engine configured to format the associated XML data according to a format governed by the format template; and

a barcode rendering engine configured to receive the associated and formatted XML data and generate a bit map representative of the bar code label.

2. The system according to claim 1 wherein the SAX processor generates a plurality of events based upon commands embedded in the format template.

3. The system according to claim 2 wherein the events are selected from the group consisting of a set printer speed event, set quantity of labels to print event, select media event, select ribbon to use event, choose paper event, use 300 dpi printer event, use 600 dpi printer event, and variable data event.

4. The system according to claim 1 wherein the format template is sent to the SAX processor and saved for use with downloaded XML data, the XML data download at a subsequent time.

5. The system according to claim 1 wherein the format template is a ZPL-based format template.
