PostScript to PDF conversion hangs or produces a blanks document

I’m working on a C# project and there are certain postscript files which cause the conversion to hang (never complete) or produce blank documents. I’m following the steps shown here to perform conversion: Postscript (.PS) to PDF conversion. I know these files are valid postscript because I can convert them with other utilities. Here’s a bare bones repro case:

using System;
using System.IO;
using System.Linq;
using Aspose.Pdf;

namespace postscript_converter
{
    class Program
    {
        static void Main(string[] args)
        {
            var noArgs = !args?.Any() ?? true;
            if (noArgs) return;

            var license = new License();
            license.SetLicense("Aspose.Total.lic");

            var options = new PsLoadOptions
            {
                WarningHandler = new WarningHandler()
            };

            var fileName = args[0];
            var document = new Document(fileName, options);
            document.Save(Path.ChangeExtension(fileName, ".pdf"));
        }
    }

    public class WarningHandler : IWarningCallback
    {
        public ReturnAction Warning(WarningInfo warning)
        {
            Console.WriteLine($"WARNING: {warning.WarningMessage}");
            return ReturnAction.Continue;
        }
    }
}

Attached is the expected outcome. I have taken this pdf and printed it using different drivers to produce postscript files. The postscript files are attached in the zip file and demonstrate the issues I’m experiencing. test1.ps produces a blank pdf, test2.ps just hangs.

Thank you for getting back to us.

Please note that the issues may appear same but the reasons could be different. The thread you are referring to was created for Exception thrown while loading a PS file. Whereas, your ticket has been logged for blank output and system hang. Since the issues are file specific and may not necessarily be same. However, we have recorded your concerns under respective ticket and will consider them while investigating your ticket. We appreciate your patience and comprehension in this regard.
