not able to print with Duplex.Vertical

[Degiorgi]

Hello,
I'm tring to print a pdf both sides. I set the Duplex.Vertical property to doc.PrinterSettings but it always print on one side. In debug I always seen the property CanDuplex with false value. My printer can print duplex and the printer name is setted before into PrinterSettings. Why the CanDuplex is always false? How can I print on both sides?
Thankhs in advance.

Hello,

Thanks for your inquiry.
Please use the System.Drawing class to test you printer and tell us the result on your side.

Code: Select all

System.Drawing.Printing.PrinterSettings ps = new PrinterSettings();
bool s = ps.CanDuplex;

Hello,

Code: Select all

System.Drawing.Printing.PrinterSettings ps = new PrinterSettings();
bool s = ps.CanDuplex;


the vale of s variable is always false

On an other printer it works fine.

thanks

Hi,

Thank you for your response.
Unfortunately, our spire.Pdf is based on the System.Drawing class in the print function.
Please try to select the double-sided option in the printing preferences and tell us the name of the printer that has problem.

Hello,

I was wondering how I can utilize the Duplex print setting to give the option to print double sided or single sided. This code seems like it would work but it always prints whatever the default settings are.

Code: Select all

PdfDocument pdf = new PdfDocument();
pdf .LoadFromFile("test.pdf");

SpirePrintOptions options = new SpirePrintOptions() // custom object
options.IsDuplex = false; // this value is set by the input.

if (options.IsDuplex && pdf.PrintSettings.CanDuplex)
    pdf.PrintSettings.Duplex = Duplex.Vertical;
else
    pdf.PrintSettings.Duplex = Duplex.Simplex;

Thanks,

Sam

Hi Sam,

Thanks for your inquiry.
I tested your code but I did not reproduce your issue, I can enable duplex or simplex printing based on the conditions. Could you please provide us with the following messages to help us work out a solution for you? You can send them to us via email (support@e-iceblue.com) or attach them here. Thanks for your assistance.
1) the details about your physical printer.
2) the version of Spire.PDF you are using.
3) your application type, such as Console App .NET Framework 4.8.

Hi,

Thanks for your feedback.
After testing, I still did not reproduce your issue, the printer we use is HP Color LaserJet MFP M281fdw. To help resolve this issue, we would like to ask if you know what your default printer settings are, duplex or simplex? we suggest that you try debugging the code to check if the single or double-sided printing setting was successfully applied.
Additionally, we recommend trying a different printer to see if the issue persists. This will help determine if the problem is related to the printer or the software.
