我尝试使用C#使用Google云打印.互联网只是一个例子,他写了Josh Goebel.我不会发布完整的示例,这是发送要打印的文件的唯一方法:

public CloudPrintJob PrintDocument(string printerId, string title, byte[] document)
    {
        try
        {
            string authCode;
            if (!Authorize(out authCode))
                return new CloudPrintJob() { success = false };

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/cloudprint/submit?output=json");
            request.Method = "POST";

            string queryString =
                "printerid=" + HttpUtility.UrlEncode(printerId) +
                "&capabilities=" + HttpUtility.UrlEncode("") +
                "&contentType=" + HttpUtility.UrlEncode("application/pdf") +
                "&title=" + HttpUtility.UrlEncode(title) +
                "&content=" + HttpUtility.UrlEncode(Convert.ToBase64String(document));

            byte[] data = new ASCIIEncoding().GetBytes(queryString);

            request.Headers.Add("X-CloudPrint-Proxy", Source);
            request.Headers.Add("Authorization", "GoogleLogin auth=" + authCode);

            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;

            Stream stream = request.GetRequestStream();
            stream.Write(data, …
