Label Printing and Device Hub with Acumatica

As you say, both are valid. I've really only ever done the first, but it's always fit my use case.

And of course thanks Daryl.

I’m referencing behavior we have seen when printing labels directly in Acumatica.  when you go to print preview the labels seem to jump off the page (too big) but you change scaling properties and it all aligns.  Having to do that every time we print. 

I know what you mean by doing one at a time but en mass (like a process screen calling the button on a form) 

I do appreciate the input.  

I had a need to print custom labels several years ago via Device Hub and wrote a blog post about it.  Printing to a Label Printer via Device Hub – Brian's Blog (acumatica.dev)  Also, you might look into Asgard Labels on the marketplace if you want a fancy solution that uses an alternative to Device Hub.

I chose the route of creating a custom label configuration screen and a set of tools to build various labels for our specific needs.  I can generate for EPL and ZPL languages spending on whether we are printing to our old Eltron printers or newer Zebra printers.  The blog post explains how to get the generated EPL or ZPL control file into Acumatica and sent to the Device Hub printer of your choice.

In 23r1, there was a minor change that I really need to document on my blog post or write a new post for the updated code.  Instead of PXGraph.CreateInstance<SMPrintJobMaint>() as noted in the blog post, you want to use the StartAsyncOperation version shown below starting with 23r1.

SMPrintJobMaint graph = PXGraph.CreateInstance<SMPrintJobMaint>();
graph.LongOperationManager.StartAsyncOperation(ct =>
    graph.CreatePrintJob(printSettings, (string)null, parameters, description, ct));
