Welcome to the ngdesktoputils wiki! This wiki provides comprehensive documentation to using the ngdesktoputils web service. This service works with the NGDesktop Client as a bridge to execute client side calls from Servoy.

Getting Started

First import the service using one of the release binaries or via Servoy's Web Package Manager.

Example Usage

//print a pdf document to default system's printer plugins.ngdesktoputils.printPDF("/Users/admin/Documents/myZebraFile.pdf");

`//print a pdf document to the specified printer`
`const options = {`
    `printer: "Zebra"`
`}`
`plugins.ngdesktoputils.printPDF("/Users/admin/Documents/myZebraFile.pdf", options);`

`//print a pdf document with options: second page only on windows, and 2 page on one side for Unix like system`
`const options = {`
    `printer: "Zebra",`
    `unix: ["-o number-up=2"], `
    `win32: ['-print-settings "2"']`
`};`

`//For available options on Unix like systems check you system's lp manual (man lp)`
`//For available Windows options check the "Printing options" of the command-line arguments for SumatraPDF: https://www.sumatrapdfreader.org/docs/Command-line-arguments`
