DEP crashes programs on Windows Server 2008 R2

If you experience random crashes on Windows Server 2008 R2, you may have a problem with the DEP (Data execution protection).

On Windows 2008 R2 there seems to be a problem with DEP. We have seen the crashes stops if users disable it for the gui.exe process or entirely. Often the crashes are logged by the Windows Event Log. According to the log they stem from random DLL files with no association with the PDF printer.

Here is how to disable it:

Open Control Panel, click on System and Security→ System → Advanced system settings. In the Advanced tab, click on the Settings button in the Performance section (the first one). In Performance Options, Data Execution Prevention has its own tab.

The odd thing about this finding is that has only been seen on Windows Server 2008 R2. Earlier or later versions of Windows Server has not shown this problem.

Autodesk/AutoCAD/Revit and PDF creation

When you want to create PDF documents from the Autodesk/AutoCAD/Revit products there are some parameters, you can use to optimize the PDF creation.

Depending on what you are printing or plotting the size of the resulting PDF may vary a lot. Especially drawings containing rasterized images or scanned images with a lot of noise dots will create huge print jobs and therefore large PDF files. If you are facing a size or performance issues, there are a couple of tricks that you can use.

  • Lower the DPI of the printer.
  • Change the raster graphics settings in your plotter configuration.
  • Reduce the paper size.

The information that goes into a PDF is a product of these settings. If you lower the DPI the 50% of what it was before then your document will typically become 4 times smaller. If you keep the DPI but doubles the paper size then the size of the print job is also approximately twice the size.

Sometimes the operating system and the printer drivers used by the PDF printer will also have an effect on size.

Here is a list of steps you can take to reduce the PDF size produced by AutoCAD.

Open the print dialog

First you open the print dialog and select the Bullzip PDF Printer. Then you click the Properties button to change the printer properties.

Raster Graphics

In the Plotter Configuration Editor, you can lower the raster image quality to a suitable value for your scenario. Try setting them to half the maximum value as shown here.

Change the DPI setting

After that you can click the Custom Properties and change the DPI. Lowering the DPI will potentially reduce the quality of the output. However, it may not mean much depending on what your PDF should be used for.

Save the plotter configuration

When you have found your preferred combination of settings, you can save the plotter configuration to a file and select that the next time you want to print to PDF. In the dialog shown here, the plotter name is now my PC3 file with all the settings.

Why do I see a trial message in my PDF

The PDF printer comes with all the features available. Some features are only meant to be used by uses with a license. However, you can still try everything without a license, so that you can decide if the feature works for what you want to do. When you use a feature that is unavailable in your current license type, you will get a trial message in the bottom of the printed page. It will look something like this:

TRIAL MODE − a valid license will remove this message. See the keywords property of this PDF for more information.

You can see why the trial message was put there and determine which type of license you need. Open the PDF file properties in Adobe Reader by pressing Ctrl+D or use the menu File->Properties.

The property will open and the Keywords section will tell you the name of the feature, you are using and which type of license it belongs to.

If you already have a license and want’s to upgrade to a higher feature level then you should write to our support.

PDF is printed as an image

When you print to PDF from some programs, you end up with a PDF that looks like a printed image instead of text. In a PDF like that, you cannot select or copy text because the PDF reader cannot determine what is text and what is graphics.

This situation occurs when the printing program sends everything to the PDF printer as an image. The recent versions of popular browsers such as Firefox, Google Chrome, and Opera does this. There is nothing much you can do about this other than trying to use another program to print. Try using the Microsoft Edge browser or Internet Explorer. They both print the text as text so that you can select it and search it in the PDF.
