The most significant change in PDFing v4 is not immediately visible as it relates to security changes in Windows Vista and Server 2008. In particular, the configuration and queue directories can no longer be located in the "Program Files" directory. In addition to this, PDFing v4 has one significant new feature and many enhancements to its existing features.

The new font selection feature in PDFing v4 will be fully licensed only when an NT service license-key is applied. However if you purchased your license-key before 26th November 2007, then the font selection feature is fully licensed for existing users.

The printing/signing feature of PDFing will, in future, be fully licensed only when an NT service license-key is applied. However if you purchased your license-key before 26th November 2007, then the printing/signing feature may be licensed by purchasing an additional printing/signing license-key.

Caution! If all your license-keys were issued before 2nd September 2006, then this version of PDFing will only work in "un-licensed" mode. Please do not proceed with installation unless you have a license-key issued on or after 2nd September 2006. If you have not yet done so, you should apply your support/upgrade license-key as soon as the installation is complete. If you have not purchased a PDFing license-key since this date, you may renew your support contract in order to receive an upgrade license-key which will allow V4 to run fully licensed, without limitations.

After a new installation of PDFing into "Program Files", the configuration and queue directories will be created in the following locations:

• Windows NT4 and earlier:
  As before, under the main \PDFing directory.
• Windows XP, 2000, 2003:
  C:\Documents and Settings\All Users\Application Data\PDFing\
• Windows Vista, 2008:
  C:\Users\Public\Public Documents\PDFing\

If Pdfing is installed outside "Program Files" or over an existing installation, then the configuration and queue directories will be located, as before, under the main \PDFing directory.

If you wish to change the locations of either directory, you can select the new menu-option [File|Sharing] which displays a form which allows you to to select a new directory location. This [File|Sharing] menu-option is only active, when PDFing is stopped, the Status form is displayed and Pdfing is running on Windows 2000 or later. The same "Sharing" form also allows you to install and un-install PDFing as a service. Because the queue and configuration directories may be opened remotely by the PDFing service client program, this form allows you to "share" these directories across the network.

Because the configuration and queue directories may be located outside the \Program Files directory, un-installing PDFing prompts you to remove these directories and their contents. If you are planning to re-install PDFing on the same PC, reply "N" or "n" when prompted. Please see upgrading to PDFing v4 for details.

The new [Fonts] page of the markup form contains new controls that change the appearance of text in "un-transformed" *SCS spooled-files. For a selected (rectangular) region of spooled-file text, or constant text that you have specified, you may:

• Relocate the text to another position on the page.
• Select a different font, either "built-in" or truetype.
• Select the size of this font.
• Select the color of this font.
• Draw (colored) line(s) around the selected region.
• Select a background color for the selected region.

Up to 20 distinct text selections or constants can be selected for font mapping.

You may now sign and encrypt the PDF files that PDFing creates.

New controls for printer quality (dots per inch), tray, bin, and duplexing have been added to the [Destination] page of the configuration and markup forms. The equivalent parameters may be specified either in the EPN= tag or in Lua for PDFing.

The controls for printer "look-up" have been moved to the [Mail-list] page of the markup-form. This control now allows for the selection of multiple printers and the PDF will be printed to each selected printer.

"Merged" PDF files will now be printed correctly.

Lua for PDFing now includes new fields in the Message. table which control new printing options. The new function Message.AddToSet() allows for the addition of external files to a set of files being created by PDFing.
