How to Print Fields that are Centered on the Label

Question

Labview 6.1 - Which VI do I call or Attribute do I set to make a String Field "Centered" on its Row on a Zebra Label? I need to specify the String Data, the Font Size and Centered about Position. One Centered field per Row (3 Rows). I am using the NewReport.vi, SetReportOrientation.vi, SetReportFont.vi AppendReportText,vi, PrintReport.vi and DisposeReport.vi

Answer 1

LabVIEW does support the windows printer driver, I was thrown off by the fact that you said "zebra label." We have a report generation toolkit that will allow you to create more advanced reports and can programatically control microsoft word and excel to create as complex of a document as you desire.
Our basic report generation toolkit that ships with LabVIEW supports simple reports and layouts. It also allows for HTML reports. You can then append any HTML formatting to the report that you desire (such as the center tag).
You could also continue to use the standard report by appending spaces to the string you are printing. For example, if you know that your printer is 80 characters wide (using a fixed width font), you can take the size of the string "len" and append (80-len)/2 number of spaces to the string. If you need help doing this, let me know.
We actually implimented a barcode label printing VI that printed an entire front panel. We created a VI that had an array of controls and we formatted the controls to our desire (one was a centered string). We then used the "print panel vi" in the block diagram. That we we simply wired the inputs to the VI and it printed the front panel to the printer onto the labels (we use this on our large shipments that have more than one item).
The ActiveX examples that ship with LabVIEW and on our website are very good starting points for creating word reports, but if you are going to use LabVIEW to manipulate Microsoft Word and Excel, I really suggest getting our Report Generation Toolkit for Microsoft Office. The RGT (Report Generation Toolkit) contains a complete set of easy to use VIs to programmatically create and edit Word and Excel documents. The Microsoft Office ActiveX interface is huge, and it is often times hard to find good complete documentation on how to perform certain tasks. The RGT VIs hide all of the ActiveX complexity and really simplify the tasks, but as a developer I really appreciate the fact that the VIs contain all of the ActiveX code on the block diagram so that I can look at them as examples and modify them to my desire. You can find out more about the RGT from ni.com, click on Products, LabVIEW, LabVIEW Addons, LabVIEW Toolsets, LabVIEW Report Generation Toolkit.
I hope some this gives you an idea you can run with.
