The x4400ps.dll file is an OEMPS module belonging to Tektronix TkGraphic from Tektronix Inc.  This is part of a PostScript OEM (original equipment manufacturer) printer driver.  A driver is a piece of software that helps your computer communicate with outside hardware such as printers or external drives.

Problems with drivers lead to your external devices not working.  If you are getting an error with this file, the chances are good that your printer may not be working right.  You can reinstall the driver if you have access to it, but you should also clean your registry.

Every file installed on your computer has an entry in the Windows registry that tells Windows how to find and use the files in programs.  A mistake in a registry entry can break your programs.
