Looking for a How to:

Issue: We need to be able to print a Bar Code Label from ServiceNow!

Fields used for Information: Number / Asset Tag / PO / Serial Number

Have been told we will need the following:

1. Able to put in dimensions of label

2. Sequence Numbering for Equipment Tag ( Needs to be 8 digits )

3. Along with Bar Code want Asset Tag and Serial Number to also print on Label

4. Printer Type ( Zebra , Intermec ,Xerox, etc )

Can anyone point me in the right direction!

Looking at some things online, looks like this has been solved already.

See: https://github.com/lindell/JsBarcode/

So I thought I'd give it a try.

I'm not sure how you'll solve the dimension issue but with this library it's not that bad.

Steps to recreate;

1.  Create UI Script and copy/paste the library code from: https://cdn.jsdelivr.net/jsbarcode/3.3.20/JsBarcode.all.min.js

2.  Create UI Macro with svg with id you will call later.

3.  Create UI Formatter calling UI Macro name plus .xml

4.  Add UI Formatter to form.

5.  Add onChange script like so to form;

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	/*
   * Run on load and on change.
   if (isLoading || newValue === '') {
      return;
   }
   */
	ScriptLoader.getScripts('jsbarcode.jsdbx', function() {
		console.log('onchange');
		JsBarcode("#code128", newValue);
/*		JsBarcode("#ean-13", "1234567890128", {format: "ean13"});
		JsBarcode("#ean-8", "12345670", {format: "ean8"});
		JsBarcode("#ean-5", "12345", {format: "ean5"});
		JsBarcode("#ean-2", "12", {format: "ean2"});
		JsBarcode("#upc-a", "123456789012", {format: "upc"});
		JsBarcode("#code39", "Hello", {format: "code39"});
		JsBarcode("#itf-14", "1234567890123", {format: "itf14"});
		JsBarcode("#msi", "123456", {format: "msi"});
		JsBarcode("#pharmacode", "12345", {format: "pharmacode"});
		*/
	});


}

Then it works onload and onchange.

This is Awesome and should be built into Service Now! 

I need to request this from our Admin, one question as we are just rolling out HAM. Is there a Asset ID Generator? Something like we can set rules on location, country and hardware type? 

@jmon feel free to connec with me on Linkedin and ask any questions you may have there. just let me knwo this is aobut this discussion here.

re: asset id generator (this would just be a string generator at taht point, tracking id's soemwhere so you dont have conflicts i assuem) I dont think this would be difficult to set up with rules on location, country and harware type.
e.g. if US laptop start with USL#, if Canada Laptop, start with CA#, etc etc.. unless those barcodes have a limit on waht characters they allow.
