	Hi, we are using the component JDiagram (Swing) and want to activate the print preview option. It works correctly, but the resolution of the preview is absolutely terrible. Look at the attachment file inside the post. Is there a way to raise the resolution and get better preview ? Thanks for help

	Hi, With what OS and Java version are you seeing this? We have some ancient code that indeed caches pages as bitmap images, but have never seen the images scale that bad... Anyway we'll try to replace the bitmap rendering with actual drawing of a scaled diagram in the next few days. Stoyan

	Well, here's untested pre-release version that now draws the print preview as vector graphics: https://mindfusion.eu/_beta/JDiagram.4.1.2.zip We are not likely to release it this year, but will try to in early January. I hope that helps, Stoyan

	Strange behavior, I don't know if this happen only with the new vector printpreview, but, when I click the "FitToPage" button in the print preview, I'm not able to see entire graph in the print preview and the print generate 2 pages (not 1). You can look the pdf (this is a scan of the printed sheet). In the same way, is is possible to remove the title and set the margin inside of the preview and printing ? Thanks for your help.

	This new build should fix it: https://mindfusion.eu/_beta/JDiagram.4.1.2.zip You can remove the header like this: diagramView.getPrintOptions().setHeaderFormat(""); You should be able to add margins via the PageFormat.Paper property and calling printPreview(PageFormat) or print(PageFormat). I hope that helps, Stoyan
