DosSetProcessCp sets the process code page of the calling process. The code page of a process is used in the following ways:

First, the printer code page is set to the process code page through the file system and printer spooler (the system spooler must be installed) when the process makes a request to open the printer. Calling DosSetProcessCp does not affect the code page of a printer opened prior to the call, and does not affect the code page of a printer opened by another process.

Second, country-dependent information, by default, is retrieved encoded in the code page of the calling process.

Third, a newly-created process inherits its process code page from its parent process.

DosSetProcessCp does not affect the display or keyboard code page.
