Hello,

We cannot reproduce the issue. Please describe your issue in detail (with pictures if possible) and a sample project.

> - I show and print with IE8 and WebViewer (IMAG0029.jpg), it print not OK, Barcode reader sometimes can not read

The barcode is displayed in the viewer as a picture.
In browsers the picture is always blurred when printing, especially looks bad when printing on thermal printers with low resolution.
High-quality printing on thermal printers is the best out from the Net/Wpf application that prints directly on the printer canvas.

> - I show with IE8 and WebViewer and Export to PDF file (IMAG0030.jpg), it print not OK.

Please send me the resulting PDF file for analysis.

Also in the next prerelease build we added the new property StiOptions.Engine.BarcodeDpiMultiplierFactor = 3
earlier it was only set to 2, i.e. when exporting the quality of barcode images was 200 dpi.
Now, by default it is set to 3, and if needed can be increased.
Even when printing from a browser it is not likely to affect the print quality.

Thank you.

Hello,
My structure network like that:
Router -> ISA Server -> Some other server include web server and join in Group Domain (config for Local network), I config Router NAT to WebServer. When I view source web page error (swfobject is undefined), I see that
All path, domain name or IP was replace by Group Domain name (name group domain local network), so all path will be incorrect.

My solution is: Move web server out Group domain, it run OK.

Hello,

Please try to set the following option:

StiWebViewerFxOptions.Connection.RelativeUrls = true;

Maybe this will help in this situation.

Thank you.
