Can not print on Single Page dgvprinter c#

There are 9 columns in datagridview when I print using dgvprinter it prints 7 columns on 1 page and other 2 on a new page. I want to print on a single page anybody helps me?
Note: There is an image on datagridview.
Here is code:
DGVPrinter printer = new DGVPrinter();
printer.Title = "Test";
printer.SubTitle = "Outgoing Stocks";
printer.SubTitleFormatFlags = StringFormatFlags.LineLimit | StringFormatFlags.NoClip;
printer.PageNumbers = true;
printer.PageNumberInHeader = false;
printer.PorportionalColumns = true;
printer.HeaderCellAlignment = StringAlignment.Near;
printer.Footer = "System generated file";
printer.FooterSpacing = 15;
printer.PorportionalColumns = true;
printer.HeaderCellAlignment = StringAlignment.Near;
printer.printDocument.DefaultPageSettings.Landscape = true;
printer.RowHeight = DGVPrinter.RowHeightSetting.CellHeight;
printer.PrintDataGridView(itemdata_datagridview);

Can't print jpg with Aspose.Pdf

I want to load in a JPEG file and print it with Aspose.Pdf in C# (.net Framework 4.8). The code I currently have is:
public void PrintImage(string fileToPrint, string printerName, string jobName)
{
System.Drawing.Image srcImage = System.Drawing.Image.FromFile(fileToPrint);
int h = srcImage.Height;
int w = srcImage.Width;
var doc = new Document();
var page = doc.Pages.Add();
var image = new Image();
image.File = (fileToPrint);
page.PageInfo.Height = (h);
page.PageInfo.Width = (w);
page.PageInfo.Margin.Bottom = (0);
page.PageInfo.Margin.Top = (0);
page.PageInfo.Margin.Right = (0);
page.PageInfo.Margin.Left = (0);
page.Paragraphs.Add(image);
var viewer = new PdfViewer(doc);
PrintUsingViewer(viewer, printerName, jobName);
}
private static void PrintUsingViewer(PdfViewer viewer, string printerName, string jobName)
{
viewer.AutoResize = true; // Print the file with adjusted size
viewer.AutoRotate = true; // Print the file with adjusted rotation
viewer.PrintPageDialog = false; // Do not produce the page number dialog when printing
var ps = new System.Drawing.Printing.PrinterSettings();
var pgs = new System.Drawing.Printing.PageSettings();
ps.PrinterName = printerName;
viewer.PrinterJobName = jobName;
viewer.PrintDocumentWithSettings(pgs, ps);
viewer.Close();
}
When I save the document instead of printing and look at it, it seems fine (the image is added). However, when trying to print the image it is not printed and the page is just blank..
I would like to print without first saving the document as a PDF and then trying to print that saved PDF. Does anyone see what I am doing wrong?

The solution was adding this line of code
doc.ProcessParagraphs();
right after this line:
page.Paragraphs.Add(image);
So the code now becomes
public void PrintImage(string fileToPrint, string printerName, string jobName)
{
System.Drawing.Image srcImage = System.Drawing.Image.FromFile(fileToPrint);
int h = srcImage.Height;
int w = srcImage.Width;
var doc = new Document();
var page = doc.Pages.Add();
var image = new Image();
image.File = (fileToPrint);
page.PageInfo.Height = (h);
page.PageInfo.Width = (w);
page.PageInfo.Margin.Bottom = (0);
page.PageInfo.Margin.Top = (0);
page.PageInfo.Margin.Right = (0);
page.PageInfo.Margin.Left = (0);
page.Paragraphs.Add(image);
doc.ProcessParagraphs();
var viewer = new PdfViewer(doc);
PrintUsingViewer(viewer, printerName, jobName);
}
private static void PrintUsingViewer(PdfViewer viewer, string printerName, string jobName)
{
viewer.AutoResize = true; // Print the file with adjusted size
viewer.AutoRotate = true; // Print the file with adjusted rotation
viewer.PrintPageDialog = false; // Do not produce the page number dialog when printing
var ps = new System.Drawing.Printing.PrinterSettings();
var pgs = new System.Drawing.Printing.PageSettings();
ps.PrinterName = printerName;
viewer.PrinterJobName = jobName;
viewer.PrintDocumentWithSettings(pgs, ps);
viewer.Close();
}
Now the image is printed correctly!

Spire.PDF prints pdf only in grayscale

I am using the free version of Spire.PDF to print a local pdf file but the print is in grayscale even though the pdf file is in color. Here is my code
PdfDocument doc = new PdfDocument();
doc.LoadFromFile(fileName);
doc.ColorSpace = PdfColorSpace.RGB;
PrintDialog dialogPrint = new PrintDialog();
dialogPrint.AllowPrintToFile = true;
dialogPrint.AllowSomePages = true;
dialogPrint.PrinterSettings.MinimumPage = 1;
dialogPrint.PrinterSettings.MaximumPage = doc.Pages.Count;
dialogPrint.PrinterSettings.FromPage = 1;
dialogPrint.PrinterSettings.ToPage = doc.Pages.Count;
if (dialogPrint.ShowDialog() == DialogResult.OK)
{
//Set the pagenumber which you choose as the start page to print
doc.PrintFromPage = dialogPrint.PrinterSettings.FromPage;
//Set the pagenumber which you choose as the final page to print
doc.PrintToPage = dialogPrint.PrinterSettings.ToPage;
//Set the name of the printer which is to print the PDF
doc.PrinterName = dialogPrint.PrinterSettings.PrinterName;
PrintDocument printDoc = doc.PrintDocument;
printDoc.DefaultPageSettings.Color = true;
dialogPrint.Document = printDoc;
printDoc.Print();
}
I have checked dialogPrint.PrinterSettings.SupportsColor returns true

CSS is not applying on creating pdf from ABC pdf

Problem:
I am passing HTML and creating pdf through ABC pdf.
But the CSS are not applied on the content and pdf created is not as expected.
Here is my code can u please suggest what is the problem or how we can apply CSS...
public static String CreateHtmlFile(String strHtmlCode)
{
String Modifiedhtml = #"<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""><html class="" _Telerik_IE9"" xmlns=""http://www.w3.org/1999/xhtml"">" + strHtmlCode;
Modifiedhtml = Modifiedhtml.Remove(Modifiedhtml.IndexOf(#"//<![CDATA["), (Modifiedhtml.IndexOf("//]]>") - Modifiedhtml.IndexOf(#"//<![CDATA[")));
string[] stringSeparators = new string[] { "PdfCreator" };
var baseUrl = HttpContext.Current.Request.Url.AbsoluteUri.Split(stringSeparators, StringSplitOptions.RemoveEmptyEntries).First();
Modifiedhtml = Modifiedhtml.Replace(#"href=""../", (#"href=""" + baseUrl));
Modifiedhtml = Modifiedhtml.Replace(#"href=""/", (#"href=""" + baseUrl));
Doc theDoc = new Doc();
theDoc.HtmlOptions.UseScript = false;
//theDoc.Width = 1125;
String s = string.Empty;
//s = File.ReadAllText(#"D:\test.html");
theDoc.Page = theDoc.AddPage();
int theID;
theID = theDoc.AddHtml(strHtmlCode);
//theID = theDoc.AddHtml(s);
while (true)
{
theDoc.FrameRect(); // add a black border
if (!theDoc.Chainable(theID))
break;
theDoc.Page = theDoc.AddPage();
theID = theDoc.AddImageToChain(theID);
}
for (int i = 1; i <= theDoc.PageCount; i++)
{
theDoc.PageNumber = i;
theDoc.Flatten();
}
theDoc.Save(#"D:\two\pagedhtml4.pdf");
theDoc.Clear();
return String.Empty;
}
strHtmlCode is the HTML of the page which we have to convert in PDF.
Thanks in advance

From the WebSupergoo doc page on the AddHtml Function:
Adds a block of HTML styled text to the current page.
HTML styled text does not support CSS. For full featured, standard CSS, you want AddImageHtml.

You are passing strHtmlCode into the AddHtml function. It looks like you really want to pass in Modifiedhtml instead.

Adding a new page using iTextSharp

I have a class that build the content for my table of contents and that works, fine and dandy.
Here's the code:
public void Build(string center,IDictionary<string,iTextSharp.text.Image> images)
{
iTextSharp.text.Image image = null;
XPathDocument rapportTekst = new XPathDocument(Application.StartupPath + #"..\..\..\RapportTemplates\RapportTekst.xml");
XPathNavigator nav = rapportTekst.CreateNavigator();
XPathNodeIterator iter;
iter = nav.Select("//dokument/brevhoved");
iter.MoveNext();
var logo = iTextSharp.text.Image.GetInstance(iter.Current.GetAttribute("url", ""));
iter = nav.Select("//dokument/gem_som");
iter.MoveNext();
string outputPath = iter.Current.GetAttribute("url", "")+center+".pdf";
iter = nav.Select("//dokument/titel");
iter.MoveNext();
this.titel = center;
Document document = new Document(PageSize.A4, 30, 30, 100, 30);
var outputStream = new FileStream(outputPath, FileMode.Create);
var pdfWriter = PdfWriter.GetInstance(document, outputStream);
pdfWriter.SetLinearPageMode();
var pageEventHandler = new PageEventHandler();
pageEventHandler.ImageHeader = logo;
pdfWriter.PageEvent = pageEventHandler;
DateTime timeOfReport = DateTime.Now.AddMonths(-1);
pageWidth = document.PageSize.Width - (document.LeftMargin + document.RightMargin);
pageHight = document.PageSize.Height - (document.TopMargin + document.BottomMargin);
document.Open();
var title = new Paragraph(titel, titleFont);
title.Alignment = Element.ALIGN_CENTER;
document.Add(title);
List<TableOfContentsEntry> _contentsTable = new List<TableOfContentsEntry>();
nav.MoveToRoot();
iter = nav.Select("//dokument/indhold/*");
Chapter chapter = null;
int chapterCount = 1;
while (iter.MoveNext())
{
_contentsTable.Add(new TableOfContentsEntry("Test", pdfWriter.CurrentPageNumber.ToString()));
XPathNodeIterator innerIter = iter.Current.SelectChildren(XPathNodeType.All);
chapter = new Chapter("test", chapterCount);
while(innerIter.MoveNext())
{
if (innerIter.Current.Name.ToString().ToLower().Equals("billede"))
{
image = images[innerIter.Current.GetAttribute("navn", "")];
image.Alignment = Image.ALIGN_CENTER;
image.ScaleToFit(pageWidth, pageHight);
chapter.Add(image);
}
if (innerIter.Current.Name.ToString().ToLower().Equals("sektion"))
{
string line = "";
var afsnit = new Paragraph();
line += (innerIter.Current.GetAttribute("id", "") + " ");
innerIter.Current.MoveToFirstChild();
line += innerIter.Current.Value;
afsnit.Add(line);
innerIter.Current.MoveToNext();
afsnit.Add(innerIter.Current.Value);
chapter.Add(afsnit);
}
}
chapterCount++;
document.Add(chapter);
}
document = CreateTableOfContents(document, pdfWriter, _contentsTable);
document.Close();
}
I'm then calling the method CreateTableOfContents(), and as such it is doing what it is supposed to do. Here's the code for the method:
public Document CreateTableOfContents(Document _doc, PdfWriter _pdfWriter, List<TableOfContentsEntry> _contentsTable)
{
_doc.NewPage();
_doc.Add(new Paragraph("Table of Contents", FontFactory.GetFont("Arial", 18, Font.BOLD)));
_doc.Add(new Chunk(Environment.NewLine));
PdfPTable _pdfContentsTable = new PdfPTable(2);
foreach (TableOfContentsEntry content in _contentsTable)
{
PdfPCell nameCell = new PdfPCell(_pdfContentsTable);
nameCell.Border = Rectangle.NO_BORDER;
nameCell.Padding = 6f;
nameCell.Phrase = new Phrase(content.Title);
_pdfContentsTable.AddCell(nameCell);
PdfPCell pageCell = new PdfPCell(_pdfContentsTable);
pageCell.Border = Rectangle.NO_BORDER;
pageCell.Padding = 6f;
pageCell.Phrase = new Phrase(content.Page);
_pdfContentsTable.AddCell(pageCell);
}
_doc.Add(_pdfContentsTable);
_doc.Add(new Chunk(Environment.NewLine));
/** Reorder pages so that TOC will will be the second page in the doc
* right after the title page**/
int toc = _pdfWriter.PageNumber - 1;
int total = _pdfWriter.ReorderPages(null);
int[] order = new int[total];
for (int i = 0; i < total; i++)
{
if (i == 0)
{
order[i] = 1;
}
else if (i == 1)
{
order[i] = toc;
}
else
{
order[i] = i;
}
}
_pdfWriter.ReorderPages(order);
return _doc;
}
The problem is however. I want to insert a page break before the table of contents, for the sake of reordering the pages, so that the table of contents is the first page, naturally. But the output of the pdf-file is not right.
Here's a picture of what it looks like:
It seems like the _doc.NewPage() in the CreateTableOfContents() method does not execute correctly. Meaning that the image and the table of contents is still on the same page when the method starts the reordering of pages.
EDIT: To clarify the above, the _doc.NewPage() gets executed, but the blank page is added after the picture and the table of contents.
I've read a couple of places that this could be because one is trying to insert a new page after an already blank page. But this is not the case.
I'll just link to the pdf files aswell, to better illustrate the problem.
The pdf with table of contents: with table of contents
The pdf without table of contents: without table of contents
Thank you in advance for your help :)
