* ''Programming language support'': DPS introduced the concept of a "<code>pswrap</code>", which allowed [[Software developer|developers]] to wrap PostScript code into a [[C (programming language)|C language]] function which could then be called from an application.

DPS did not, however, add a windowing system. That was left to the implementation to provide, and DPS was meant to be used in conjunction with an existing windowing engine. This was often the [[X Window System]], and in this form Display PostScript was later adopted by companies such as [[International Business Machines|IBM]] and [[Silicon Graphics|SGI]] for their workstations. Often the code needed to get from an X window to a DPS context was much more complicated than the entire rest of the DPS interface{{citation needed|date=March 2011}}. This greatly limited the popularity of DPS when any alternative was available{{citation needed|date=March 2011}}.
