Having same issue
@githubsamurai @Dev-MRob any resolution? @dymosoftware would really love to make this work. Having to dump info off to a windows service from the web application to get this to work now.
Hi, sorry for late response. Please try with latest version of SDK.
@dymosoftware
Here's what I'm getting with the new SDK and this very basic source code:
Source Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DymoSDK.Implementations;
namespace web_test.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Title = "Home Page";
DymoSDK.App.Init();
//var printers = DymoSDK.Implementations.DymoPrinter.Instance.GetPrinters();
DymoPrinter.Instance.GetPrinters();
return View();
}
}
}
Error
System.Exception
HResult=0x80131500
Message=Error getting printers
Source=DymoSDK
StackTrace:

I am having the same issue. Did you find a solution ?
I found that I had to set the compile to Target CPU: x86 instead of Any CPU and then it worked for me, but I don't remember if that was the same error I was getting, I just know I could only get it to work with x86.
I did the same as @skillsinc-Ed as a stop gap. Our solution initially works but then the DYMO dll crashes the spooler at what seems to be random points. Makes the solution unreliable. I'm planning on giving them a call next week.
In a WPF application I load my labelprinter dll dynamically (via System.Reflection.Assembly.CreateInstance and AppDomain.CurrentDomain.AssemblyResolve). In my labelprinter dll I have references to the required DYMO.Connect and SkiaSharp packages. This dll and all the referenced ones are situated in a submap in the WPF application's bin map. I have this dll loading technique working for several other 3rd party software components. Now when I run my application this way I get the "Error getting printers" exception on calling the DymoSDK.Implementations.DymoPrinter.GetPrinters().
As a sorta workaround I found that adding a "probing" element to the app.config of the WPF application "solved" the issue:
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1"/>
</startup>
<!-- Discover assemblies in /lib -->
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="lib" />
</assemblyBinding>
</runtime>
</configuration>
All of my projects are the same... .NET Framework 4.7.2. All of them are set to Any CPU and Prefer 32bit is off. I have a winforms app that the SDK works fine on but when i installed the SDK in a ClassLibrary i get this error. I'm also attaching a screenshot if it helps.
Thanks!![2021-01-09_11-32-53](https://user-images.githubusercontent.com/66388657/104103388-d8f95b00-526f-11eb-8974-7b55fd542859.png)
