Spooling of PDF print jobs

Installing the PDF printer and printing PDF documents requires that the Windows Spooler service is running on the machine.

You can change the spooler settings under printer properties on the Advanced tab. The default settings for newly installed printers are shown in the screenshot below.

If you prefer other settings, you can easily change them to fit your needs. You can also bypass the spooling of your documents by selecting Print directly to the printer. Please note that this option still requires the spooler service to be running when the printer is used.

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.

Font problems in PDF document

Sometimes you can experience font problems when printing to PDF. Many different problems can cause fonts to be missing, render as boxes or look like strange unknown characters or artifacts. Usually font problems are related to specific application. Some applications may be using the Windows print system in a different way than other programs. This can cause font problems that only occurs when printing from these systems. Here are some tips on what you can try to solve the font problems.

Embedding fonts in your PDF

The PDF printer supports different levels of font embedding. When you embed a font in your document then the information about the fonts are saved with your PDF file. When fonts are not embedded then the PDF may show strange things such as small squares or nothing at all when you open the PDF. By default, the printer embeds the characters that are used from the fonts in the PDF. You can change this setting from Subset to All and hope that the extra font information solves a font problem that you may be experiencing. Font embedding is changed in the Options dialog.

TrueType Font Download Option

The second thing you can try is to change the TrueType font download option in the printer’s advanced settings. It is set to Automatic by default but changing it to outline may solve the missing fonts problem.

Normally, you can get to this dialog when you print. In the Print dialog where you select a printer there is a button named Preferences. Click that button and then click the Advanced button.

If you want to change the default behavior to outline then you should open the Advanced Options dialog from the printer properties in your list of printers. On the Advanced tab, you can set the printing defaults.

Printer Options Dialog

The printer’s options dialog is where you configure all the default settings for the PDF printer.

Opening the options dialog

You open the options dialog from the Windows Start Menu. In Windows 10 you can open the start menu and start typing the word options. Then it will show up in the list.

In Windows 7 you can also find the options dialog in the start menu. Browse to the Bullzip folder and click the PDF Printer menu entry.

Once the dialog is open, you can start changing the default values. Click Apply or OK to save the changes.

Paper Trays on the PDF Printer

By default, the PDF printer does not have any paper trays installed. However, you can add virtual trays to your PDF printer if you want.

In this example, we will add 5 trays for debugging purposes. The trays will be named Tray 1 through 5 and they will each add the tray name to the printed page.

To install the trays, you simply add the following lines to the end of the printer’s PPD file:

*InputSlot Tray1/Tray 1: "gsave /Times-Roman findfont 30 scalefont setfont newpath 10 10 moveto 1 0 0 setrgbcolor (Tray 1) show grestore"
*InputSlot Tray2/Tray 2: "gsave /Times-Roman findfont 30 scalefont setfont newpath 10 10 moveto 1 0 0 setrgbcolor (Tray 2) show grestore"
*InputSlot Tray3/Tray 3: "gsave /Times-Roman findfont 30 scalefont setfont newpath 10 10 moveto 1 0 0 setrgbcolor (Tray 3) show grestore"
*InputSlot Tray4/Tray 4: "gsave /Times-Roman findfont 30 scalefont setfont newpath 10 10 moveto 1 0 0 setrgbcolor (Tray 4) show grestore"
*InputSlot Tray5/Tray 5: "gsave /Times-Roman findfont 30 scalefont setfont newpath 10 10 moveto 1 0 0 setrgbcolor (Tray 5) show grestore" 

The PPD file is normally located here:


Just save the changed the PPD file. Windows will automatically detect the change and use the new settings.

When you print from a program like Notepad and select Tray 3, you will see something like this:

Note: Paper trays are also called paper bins or paper sources.

Hide the print dialog

One of the great features of the PDF printer is that you can automate a lot of things. Hiding the print dialog is one of the popular things. It is very easy to do that. All you have to do is follow the steps listed in this article.

Open the options dialog

You can open the options dialog from your Windows start menu. This is where you set all the default values that are used when the printer is activated.

On the Dialogs tab you can specify when the dialogs should be shown. There are two dialogs: A Save As, which can be shown to just get a file name from the user. The settings dialog is the full dialog, which shows all the available features to the user. The dialogs will remain hidden if you set both settings to never.

Specify a File Name

When the saving is automated then it needs an automatically generated file name. By default, the printer will save a document on the user’s desktop and create a name based on the document title in the print job. There are lots of different macros that you can use to create names automatically.

You can also remove the Confirm Overwrite and Confirm folder creation to silence it even more.

Click OK to save the settings for the next print job.

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.

Adding a printer manually

Sometimes the installer fails to add the PDF printer to your list of installed printers. There can be many reasons for that. Maybe your system does not have the normal drivers available because your system administrator deleted them to save disk space. Maybe your spooler service is disabled for some reason or other things could be the problem.

When you troubleshoot the printer installation, it can be a good test to see if you can install the printer manually through the normal Windows interface to do so. This article will show you the steps to do that on a Windows 10 system. Most other versions of Windows have similar dialogs but they may look slightly different.

Open your Devices and Printers window.

Click the Add a printer menu item.

Click The printer I want isn’t listed

Add a local printer

Choose the BULLZIP port

Locate the Microsoft PS Class Driver and select it.

Replace the driver if needed

Name the printer
