Slow Printing PDF

[douglasalonso]

I have the following problem, I get a base64 string, record a PDF file and load the loadFile () using the PdfDocument spire.pdf, printing is very slow. Picking up the same file and printing with Adobe Reader there is the option to Print as image, deselecting this printing option is very fast. Is there a way to do this by the component?

The printer is used lexmark ms811dn

Unfortunately I do not permit the company to pass the string 64 because they are sensitive data.

Still thank you and excuse the English by google translator

Hi douglasalonso,

You could only provide a sample file to show the issue.

I sent a sample file

I did another test, using PDFDocument.SaveFile () and then SaveDialog, the PDF file is generated it is as an image format.

I have another PDF file generated by the reporting services this saving by SaveDialog maintains PDF text format.

I believe this is the problem of delays in printing, the files generated by PDFDocument.Print are added in Windows print queue, but between an impression and another the printer takes a few seconds to start the next printing.

The printer lexmark ms811dn has the capacity to print 60 pages per minute, however this printing 20

Hi douglasalonso,

I am sorry that I don't understand the method to generate the pdf as an image format. Could you please provide us your snip codes to help us do an investigation?

Hi,

this is the code I'm using to send to printer

PdfDocument doc = new PdfDocument();
byte[] bytes = Convert.FromBase64String(base64String);
doc.LoadFromBytes(bytes);
doc.PrintDocument.DocumentName = fileName;
doc.PrintDocument.PrinterSettings.PrinterName = printerName;
doc.PrintDocument.Print();

The system sends it to the print queue, every two or three sheets printed the printer will stop a few seconds to start a new printing.

One of the tests we did was convert this array into a file and save it to disk, then upload the file and send to print. Using spire.pdf had the same problem of slow, the other test was open and print the adobe reader was too slow, we can only change the print speed going in preferences Adobe Reader and unchecking the checkbox print as picture, I am sending attachment the image with this option the printer prints straight without stopping

Hello,

Thanks for the information. Exactly, our product prints the pdf document in the image way. And here is another way you could try.

Code: Select all

MemoryStream ms = new MemoryStream();
PdfDocument pdfDoc = new PdfDocument();
pdfDoc.LoadFromFile(fileName);
pdfDoc.SaveToStream(ms, FileFormat.XPS);
ms.Position = 0;
XpsPrint.XpsPrintHelper.Print(ms, @"\\192.168.1.104\HP LaserJet P1007", "SpireTest",true);

Hello,

Sorry for the delay to respond, we did the test with the option to print in XPS, for some reason in the network printer did not work. I returned to the previous solution using spire.pdf, after several tests and monitoring the external calls of the system, we came to the conclusion that the component spire.pdf is printing perfectly within the expected, we had an improvement also when we installed the universal driver more Current lexmark and lastly we did a final test on the printer model that the documents will print and the printing speed was very satisfactory.

Thank you very much for your attention.

Att,
