Notes and Restrictions on SkyPDF Pro MT Driver


Please note the following restrictions and precautions when using SkyPDF Pro MT Driver.

Matters Related to Supported Applications

  1. SkyPDF Pro MT Driver does not support printing from UWP applications. Therefore, the following problems may occur if you specify the Driver when printing (converting to PDF) from a UWP application.
    • If the Driver is set to direct Print Settings*, problems such as the inability to create PDFs may occur.
      • At the “Devices and Printers” screen, right-click on [SkyPDF Pro MT Driver]  >  [Printer Properties]  >  [Advanced] tab  >  [Send print data directly to printer]
    • Printing from a UWP application may cause the process to become unresponsive or appear to have stopped.
  2. Even with supported applications, PDF accuracy may be impaired in rare cases due to conditions such as layout and file size.
    When using Visio, any Bold, Italic, or ItalicBold characters that have been entered may be recognized as graphics and converted to PDF instead of text. In some cases (see the example below), even standard typefaces may be recognized as graphics.
    (Example) When using the standard font “MS P Gothic” in Visio, all text and graphics are recognized as graphics if the print resolution is 300 dpi or less. Additionally, all characters with a font size of 86 pt or larger at a printing resolution of 600 dpi, 43 pt or larger at 1200 dpi, and 22 pt or larger at 2400 dpi are recognized as graphics.
  3. When using Visio, due to its specifications, changes made to the paper orientation in the Print Settings will not be reflected.

Matters Related to Page Settings

  1. Even when the [Remove blank pages] setting is enabled, blank pages in PowerPoint files will not be removed.
  2. Even when the [Remove blank pages] setting is enabled, in Word files, only blank pages (created with [Insert]  >  [Page Break]) that do not contain line feed characters will be removed.
    Blank pages created by pressing Enter or by creating blank pages (created with [Insert]  >  [Blank Page]) will not be removed because they contain line feed characters.
  3. If the source document contains a large number of objects such as links, processing related to the [Optimize for web view] settings may not complete.
  4. The print results may differ between a PDF output using SkyPDF Pro MT Driver with black and white set on the application side and a PDF output with black and white set on SkyPDF Pro MT Driver.

Matters Related to PDF Standards

  1. PDFs output as PDF/A may not be properly pre-flighted in Adobe Acrobat in some cases if the CID Set assigned for the originally embedded font is incomplete.
  2. If a character code is used that is not assigned to characters in the external character area, PDF output to the PDF/A standard may not be possible.

Matters Related to Embedded Fonts

  1. If a Type 1 font is set in the [Enbed Fonts] tab settings in SkyPDF Pro MT Driver and a document created using that font is converted to PDF, unintended results such as an error message appearing when opening the PDF or Type 1 font portions appearing blank may occur, depending on the application.
    <Measures>
    Please take one of the following measures.
    1. When using Type 1 fonts, fonts are not embedded.
      • However, since embedding is not performed, if the corresponding font is not installed in the environment where the PDF file is opened, it may be displayed with an alternative font.
    2. Changing Type 1 fonts to a different font.
    3. Open a PDF file with this product.

Matters Related to Compression Options

  1. The compression option method used may vary depending on the application and environment.
    For example, even when the same TIFF image from the same application is converted to PDF, the “Monochrome image compression” setting may be enabled on a 32-bit OS, and the “Color/grayscale image compression” setting on a 64-bit OS may be enabled.

Matters Related to OS Functions

  1. When printing with the [Output to File] option enabled in the OS, the following settings in the [Page Settings] tab of the Driver do not apply.
    • Output Settings
    • Setting When File Already Exists
    • Add the Date to the File Name
    • Add the Process ID to the File Name
    • Open Files after Saving

Matters Related to Hyperlink

  1. Only 1 hyperlinked character string is possible.
  2. If a hyperlinked character string contains any of the following characters, the rest of the text will not be hyperlinked.
  3. ( ^ \ | ' "
  4. (Example) If “https://msdn2.microsoft.com/ja-jp/library/ms742418(VS.80).aspx” is converted to a PDF, the hyperlinked character string will only contain “https://msdn2.microsoft.com/ja-jp/library/ms742418”.
  5. When using Ichitaro, if there are characters and a space immediately before the e-mail address, the space is ignored and the characters and the address together is recognized as a hyperlink.
    (Example) In the case of “e-mail ii-help@skycom.co.jp”, the hyperlink will not be “ii-help@skycom.co.jp”, but will instead become “e-mailii-help@skycom.co.jp”.
  6. When using Visio, hyperlinked character strings cannot be recognized when creating PDFs because Visio splits text data. However, hyperlinks can be assigned if pasted from other applications (Word, etc.).
    • Font conditions for each item must be met.
  7. When using Excel or PowerPoint, special symbols are treated as a separate font, so normal characters and special symbols become separate strings and are not recognized together as one hyperlinked character string.
    (Example) Special fonts: Estrangelo Edessa, Gautami, Latha, Mangal, Raavi, Shruti, Tunga

Matters Related to the Font on the Print Screen

  1. When using an English OS that does not have the “MS UI Gothic” font, the text on the print settings screen of SkyPDF Pro MT Driver becomes larger, and some displays disappear outside the frame. This can be avoided by installing the “MS UI Gothic” font or installing Microsoft Office.
