我必须打印发票，但是，问题是我需要指定纸张的尺寸，但是，我不知道报告的高度，它将被打印为连续的pos打印机。 / p>
这是我创建文档的方式：
public async Task<FileResult> CreatePdf(int id)
{
MemoryStream workStream = new MemoryStream();
StringBuilder status = new StringBuilder("");
DateTime dTime = DateTime.Now;
//file name to be created
string strPDFFileName = string.Format("SamplePdf" + dTime.ToString("yyyyMMdd") + "-" + ".pdf");
Rectangle envelope = new Rectangle(216, 14400);//margenes
// Document doc = new Document(envelope, 0, 0, 0, 0);
Document doc = new Document(envelope, 0, 0, 0, 0);
//Document doc = new Document();
doc.SetMargins(0f, 0f, 0f, 0f);
//Create PDF Table with 5 columns
PdfPTable tableLayout = new PdfPTable(5);
doc.SetMargins(0f, 0f, 0f, 0f);
//Create PDF Table
//file will created in this path
string strAttachment = Server.MapPath("~/Downloadss/" + strPDFFileName);
PdfWriter.GetInstance(doc, workStream).CloseStream = false;
doc.Open();
//Add Content to PDF
doc.Add(await Add_Content_To_PDF(tableLayout, id));
// Closing the document
doc.Close();
byte[] byteInfo = workStream.ToArray();
workStream.Write(byteInfo, 0, byteInfo.Length);
workStream.Position = 0;
//
// Summary:

return File(workStream, "application/pdf", strPDFFileName);
