Release notes:

1) Supported
- Microsoft Windows 8
- Microsoft Windows 8.1
2) Fixed
- When printing a job with the Duplex, Resolution, Paper Type, or Input Tray setting configured in an application, the specified setting that was configured is ignored.
- Missing characters might occur if the font contains a large amount of bitmap data.
- When printing a booklet with a custom paper size and specific paper type, the first page of the printed result is a blank page.
- If two drivers that are installed on a Windows XP machine contain the same rc4manNT.dll files but each file is a different version (one is v5.2.7.7 or later and the other is before v5.2.7.7), the Printer Properties might fail to open and an error with exception code 0xc0000005 might occur.
- When printing a watermark from WordPad or Microsoft Paint, "URGENT" and "ORIGINAL" do not appear in the Watermark list. In addition, when "(None)" is selected, "ORIGINAL" is shown in the print preview and appears in the printed result.
- Some driver settings that are configured using the "Printing Defaults" button are not inherited when installed on point and print clients. This issue occurs when the server's OS is x64-based and the client's OS is x86-based, or vice versa.
3) Others
- Improved performance when printing images that overlap text.
- Added CAT (Catalog) files which were released from Microsoft (WHQL).

About Printer Driver:

Windows OSes usually apply a generic driver that allows computers to recognize printers and make use of their basic functions. In order to benefit from all available features, appropriate software must be installed on the system.
