Poor PDF output quality when rendering PrintDocument using Aspose.Pdf.PrintController

Hi,
We just renewed & upgraded (to 21.5) our Aspose.Total .Net License because we were looking for a way to render a .Net PrintDocument to a PDF document.
The Aspose.Pdf.PrintController seemed to do the trick with only a few lines of code, but we were rather disappointed by the output.
If we render the PrintDocument to a StandardPrintController(); and print it to an XPS printer or Microsoft PDF printer, the output is clean as expected, and is rendered as text.
We went for the Aspose.Pdf.PrintController in the first place because we want to be able to render documents to PDF without a dependency to a pre-installed printer.
But when we now render the PrintDocument using the Aspose.Pdf.PrintController, the output seems to be rather blurry, and it is rendered as 1 giant image per page instead of text.

Is there any way the print quality can be improved ?
This is the code we used

Stream license = new FileStream(@"E:\TFS_FH\rcx\dev\Source\Framework\PostLibrary\Aspose.Total.NET.lic", FileMode.Open, FileAccess.Read);
            new Aspose.Pdf.License().SetLicense(license);
            streamToPrint = new StreamReader(@"c:\temp\LorumIpsum.txt");
            try
            {
                Aspose.Pdf.PrintController pc = new Aspose.Pdf.PrintController();
                pc.FileName = @"c:\temp\LorumIpsum.pdf";
                               
                PrintDocument pd = new PrintDocument();
                PaperSize a4 = new PaperSize("A4"
                    , (int)Math.Round(21.0f * 72f / 2.54f, 0, MidpointRounding.AwayFromZero)
                    , (int)Math.Round(29.7f * 72f / 2.54f, 0, MidpointRounding.AwayFromZero));          
                pd.PrinterSettings.DefaultPageSettings.PaperSize = a4;
                pd.DefaultPageSettings.Landscape = false;
                pd.DefaultPageSettings.PaperSize = a4;

                pd.PrintController = pc;                

                pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
                
                pd.Print();
            }

            finally

            {
                streamToPrint.Close();
            }

The printPage handler is basically only printing text using MeasureString & DrawString :

s = ev.Graphics.MeasureString(line, font, layoutArea, stringFormat, out fitCharCount, out linesFitted);
PointF location = new PointF(ev.PageSettings.PrintableArea.Left, yPos);
using (SolidBrush drawBrush = new SolidBrush(Color.Black))
    ev.Graphics.DrawString(line, font, drawBrush, new RectangleF(location, s));
yPos = yPos + s.Height;

Hi @asad.ali thank you for above message.
Where can we follow the status of issues PDFNET-49756 & PDFNET-50123 ?
If you do also manage your issues in Jira, do we - customers - have access to your Jira backlog to follow-up the progress of the issues ?
Or is the forum the only place where we can see updates ?

Kind regards

Hi @asad.ali
Can you give me a high level estimate on the ETA of this fix PDFNET-49756 & PDFNET-50123?
Is it a matter of days / weeks / months ?
This is blocking our own development, and if this takes too much time to fix on your end, we will have to look for an alternative solution.

Hi,

Last year, we renewed our Aspose Total subscription to version 21.5 because we were looking for the new functionality to render .Net PrintDocuments as a PDF document without any dependencies.

After having purchased the new Aspose subscription, we noticed that the quality of the documents generated by the Apose PDF PrintController is very poor, and is not usable in our production environment.

Documents are being rendered as a poor quality image instead of high quality text.

I’ve logged a support request under PDFNET-50123, and it seems there is a duplicate issue PDFNET-49756 “pages are converted into images while printing” from another member.

See Poor PDF output quality when rendering PrintDocument using Aspose.Pdf.PrintController

Since then, nearly 10 months has passed, the issue is still not solved, and no progress has been reported on this subject.

Recently we received the renewal expiration warning for order 210624145700 , and our management is asking if we should renew our subscription under the given circumstances.

As mentioned, we did an upgrade to the latest version, and bought a new subscription, for a feature which is still useless after nearly 1 year.

Please advise.
Kind regards,
Gantner ALM

Hi,

Shelia from your sales department contacted us yesterday regarding the renewal of our order & licenses of Aspose.Total.
However, since this issue has still not been resolved (PDFNET-49756 & PDFNET-50123) our management has a bad feeling about renewing our licenses.
Last contact was 2 months ago, where an update was promissed “soon” but we haven’t received answer or any commitment regarding ETA.
Please advise.

Please advise.
Kind regards,
Gantner ALM
