doesn't work with .net 6 #51

Open toristorii opened 2 years ago

toristorii commented 2 years ago

With .NET 6, DymoSDK.App.Init() fails with the following exception:

Could not load file or assembly 'DYMO.LabelAPI, Version=1.4.3.37, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.'

I saw a similar issue here for .net 5. Is .net core going to be supported? Or are we forced to continue to use the old Dymo Label SDK 8? (which does appear to work)

binn commented 2 years ago

I am also having this issue with .NET 5

eljayg commented 2 years ago

@dymosoftware any update on this?

dymosoftware commented 2 years ago

DymoSDK nuget is currently targeting netstandard2.0 as of today. It will provide multi targeting for net5, net6 in future release. We don't have timeline for the project yet.

Cross-referencing same issue in #16

Is there anything we can do to help? Why not leverage the power of GitHub and the open source community to assist with this migration?

eljayg commented 2 years ago

@dymosoftware please escalate this issue. .NET 6 and .NET Core 3.1 are the only Microsoft supported versions right now.

@dymosoftware the samples are also too old and require the .NET 4.6.1 targeting pack which is not available from MSFT. We really need this to work in .NET Core 6. We need it for a blazor app.

toristorii commented 2 years ago

@dymosoftware Are you planning on supporting the people that write software for your label printers? Or would you prefer we software developers look into other label printing solutions?

brian-douglas commented 2 years ago

We switched to Brother. So far, so good.

csobsidian commented 1 year ago

Does the Brother solution require additional software installs like the Dymo solution (Dymo Connect)? I too am looking for a label writing Blazor solution.

brian-douglas commented 1 year ago

We didn't need any external software. It's much simpler to work with.

mschulz531 commented 1 year ago

Can't believe that Dymo is not supporting .NET Core 6 (or even .NET Core 5).

Looks like Brother is the way to go. Goodbye Dymo

mschulz531 commented 1 year ago

We didn't need any external software. It's much simpler to work with.

Brian, can you provide any details about how you are using Brother software? I looked into this and the Brother SDK is 10 years old and only appears to support .NET Framework 4.6.

I'm shocked that there do not appear to be any label printer SDKs that support any current .NET technologies.

Thanks for any help you can provide.

brian-douglas commented 1 year ago

The thinking is to treat the Brother printer just like any other printer, but you have to send it a “page” with a very small custom page size. We have a Winforms app which uses RDLC reports to send labels. It’s straightforward if you adjust the page size in the report itself. Just pretend it’s just any old printer.

Another interesting observation: in this dymo GitHub, nobody from the company (@dymosoftware, hint hint) seems to be reading (or caring about) the conversation going on here. Another reason to switch, IMO.

toristorii commented 1 year ago

They certainly don't seem to realize that software developers represent hundreds if not thousands or tens of thousands of individual printer sales. shrug

DaveSlinn commented 1 year ago

@brian-douglas suggestion is exactly how I ended up solving the problem for the Dymo labeller. I no longer use the Dymo software or SDKs. My code creates HTML which it converts to PDF and then sends to the printer. It's not very efficient, but it runs "fast enough".

using SelectPdf;
using System;
using System.Drawing;
using System.Drawing.Printing;
using System.IO;
...
        public class LabelFields
        {
            public string Name { get; set; }
            public string Address { get; set; }
            public string OrderName { get; set; }
        }

        public static void PrintLabel(this LabelFields labelFields)
        {
            var html = Resources.label_template;

            html = html.Replace("{CUSTOMER_NAME}", labelFields.Name);
            html = html.Replace("{CUSTOMER_ADDRESS}", labelFields.Address.Replace("\r\n", "<br />"));
            html = html.Replace("{ORDER_NUMBER}", labelFields.OrderName.Replace("#", ""));

            var converter = new HtmlToPdf(420);

            converter.Options.PdfPageSize = PdfPageSize.Custom;
            converter.Options.PdfPageCustomSize = new SizeF(252f, 79.2f);
            converter.Options.PdfPageOrientation = PdfPageOrientation.Landscape;

            var doc = converter.ConvertHtmlString(html, "/");

            var stream = new MemoryStream();
            doc.Save(stream);
            var stream2 = new MemoryStream(stream.ToArray());

            PrintPDF("DYMO LabelWriter 450", "Plain", 1, stream2);

            doc.Close();
        }

        private static bool PrintPDF(string printer, string paperName, int copies, Stream stream)
        {
            try
            {
                var printerSettings = new PrinterSettings
                {
                    PrinterName = printer,
                    Copies = (short)copies,
                };

                var pageSettings = new PageSettings(printerSettings);

                foreach (PaperSize paperSize in printerSettings.PaperSizes)
                {
                    if (paperSize.PaperName == paperName)
                    {
                        pageSettings.PaperSize = paperSize;
                        break;
                    }
                }

                using (var document = PdfiumViewer.PdfDocument.Load(stream))
                {
                    using var printDocument = document.CreatePrintDocument();
                    printDocument.PrinterSettings = printerSettings;
                    printDocument.DefaultPageSettings = pageSettings;
                    printDocument.PrintController = new StandardPrintController();
                    printDocument.Print();
                }

                return true;

            }
            catch (Exception)
            {
                return false;
            }
        }

freakshock88 commented 1 year ago

@DaveSlinn thanks for your example. I've tried running your sample in a .NET 6 console app but can't get it to build. What NuGet packages are you using exactly? And do you know if it's possible to run this on Linux?

DaveSlinn commented 1 year ago

Here are the NuGet packages my app has that are used for printing labels.

    <PackageReference Include="PdfiumViewer.Native.x86_64.v8-xfa" Version="2018.4.8.256" />
    <PackageReference Include="PdfiumViewer.Updated" Version="2.14.4" />
    <PackageReference Include="Select.HtmlToPdf.NetCore" Version="22.1.0" />

I run it on Windows, so not sure - you'd probably have to check the individual NuGet packages you're referencing.

77vetter1 commented 1 year ago

We were having trouble using the sdk and found if the Dymo Connect service is not started by a user with Admin privileges we could not print. But once the service is started with a user who has admin privileges then we were able to print labels using the SDK. Not sure if it is particular to our corporate policy's but wanted to share this is what we found.

I have the same problem...I have an application in c++ that calls a library in c# and I have this error, how can I solve?

luis-aguirree commented 1 year ago

Same issue here, I tried also connect via COM but I can'f find de DYMO.DYMOaddin anymore, the only way that I could handle this issue was using the Javascript sdki but is useless when your project also includes tablets android.

jspanoeddson commented 1 year ago

same issue, ****"System.IO.FileNotFoundException: 'Could not load file or assembly 'DYMO.CrossPlatform.Common, Version=1.4.3.37, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified using dot net 7

queueslikely commented 1 year ago

@dymosoftware Are there any plans to support .net core in the near-ish future?

We were considering paying the DYMO own-brand label tax because of how much easier this SDK made things, but it's not ideal when it (and the DYMO Connect software) come with a version of SkiaSharp with the libwebp vulnerability.

A minor shame as well when everything else of ours is .net core :(

adam-b-jones commented 1 year ago

Any updates at all on this? Receiving the same error as others, "Could not load type of field 'DymoSDK.Implementations.DymoPrinter:PrintCategory' (1) due to: Could not load file or assembly 'DYMO.CrossPlatform.Common, Version=1.4.4.21, Culture=neutral, PublicKeyToken=null' or one of its dependencies."

Using .NET 7, it's a Blazor WebAssembly project. Not having any luck getting it to work.

fruitmans commented 8 months ago

Same issue and i was unable to fix it for me. Even the WPF sample project doesn't work in Visual Studio 2022. This WPF sample project gives me the same error.

The availability of the SDK was of great value for the tooling in which i use is. Now we want to upgrade to support the 550 and all its functions but i am unable to build the project anymore.

@dymosoftware: is there any update on this topic or is it time to switch to another printer which do provide support?

0x427279 commented 3 months ago

We've purchased one of these printers as we're looking to integrate a label printer into our warehouse goods in/out facility, unfortuantely, as our corporate app is using versions of dotnet that you don't support (despite me having written the code to drive the printer with your SDK), I'm going to have to go back to the drawing board and look for a different product to deploy. Is there any update on this @dymosoftware since your comment on 17th May 2022?

skillsinc-Ed commented 3 months ago

Why not just make it a standalone app that you call from your existing corporate app. I do this all the time with Macros in our ERP system since I can't modify the ERP to integrate my own code. I just compile it into an exe and then launch it with command line arguments for the information I need on the sticker.

I had a similiar thought (and have built the app to do it), unfortunately, due to the nature of the contracts we hold, we are not allowed to use unsupported software on our systems, and .net standard 2.0 falls into this category.
