5.0 Printing from HTML

There are numerous ways to print from the Naurtech Web Browser. Once a

printer is configured, print content may be specified via a special META tag, the

CEBrowseX or “external” objects, the custom PRINT tag, or with any ActiveX

control designed to print from a browser.

The Naurtech Web Browser maintains the printer configuration within the

Session configuration dialogs. Here you may specify a serial attached,

Bluetooth, IrDA, or network attached printer. We support both Windows Print

Queues and direct-to-port printing for network printers. See the CETerm User’s

Manual for more details on configuring a printer.

All of the techniques for specifying print content allow common escape

sequences to be embedded which will be converted to non-printable characters.

These include the carriage return (CR – “\r”), linefeed (LF – “\n”), and general

hexadecimal bytes (0xXX).

5.1 PRINTING WITH A META TAG

See the “ZebraLabel_Print” and “ZebraLabel_Complete” identifiers in the META

tag section for details on initiating a print from a META tag.

5.2 PRINTSTRING AND PRINT METHODS

The PrintString method on the CEBrowseX control and the Print method on the

“external” object behave similarly. In both cases, a string is constructed and sent

to the current printer.

<a href="Javascript:myprint();">Test External Print</a>

function myprint()

{

external.Print(

"! 100 200 200 1225 1\r\n" +

"TEXT 0 2 1 0 Vendor\r\n" +

...

"JOURNAL\r\n" +

"PRINT\r\n"

);

}

</script>

5.3 NAURTECH:PRINT TAG

The custom PRINT tag is supported for compatibility with other browsers. See

the Symbol Web Client section for a discussion of this tag.
