It could be related to printer driver settings where the default setting are low quality.  It may require some work with the DEVMODE structure to set the correct quality settings in the QPL Customer Custom printer before printing.

    QP.LoadFromFile("PrintDocumentTest.pdf", "");
    int op = QP.PrintOptions(1, 0, "Hello World");

    string printer = QP.NewCustomPrinter(QP.GetDefaultPrinterName());

    int ret = QP.SetupCustomPrinter(printer, 5, 1);  // Print Quality = High

    ret = QP.PrintDocument(printer, 1, MyPageCount(), op);

Hi,

as JanN wrote: you try to print an image (made by rendering) on a device with very low resolution.

Let's assume every line has 4mm high letters on 9 needles, so the printer realizes much less than 72dpi. Thats less as on screen! And in the image, there is not exactly one pixel for every needleposition on paper. Needles and pixels dont match. So it cannot be quality. Its the same as with fax-communication.

It is rather sure that adobe goes another (more complicated) way, depending more on the possibilities of use printer.

You should think about another way (textextraction, printing without QPL).


Cheers,
Werner

Please keep in mind, that QuickPdf prints differently than Adobe Reader. QuickPdf renders the pages and then submits an image to the printer. Whereas Adobe really communicates with the printer driver and submits text if possible.

Someone correct me please if I'm wrong.

EDIT: Printing images on a matrix printer in most cases is a bad idea.

Did You try to print that PDF from Adobe Reader to that matrix printer and compare results?

Hi,

if i print on a matrix printer the letters in the printout are distorted/crackled, it is hard to describe. It's like there is a scaling which is not calculated properly. The same printout on a laserprinter is printing fine.

Do you have any idea? I use quickpdf 7.24 and

  qp.PrintDocument(newpr, 1, qp.PageCount, qp.PrintOptions(0, 0, reportname));

does anyone have an idea?

Thanks,

Martin
