— Command: hardcopy [-h] [file]

(C-a h, C-a C-h)
Writes out the currently displayed image to the file file, or, if no filename is specified, to hardcopy.n in the default directory, where n is the number of the current window. This either appends or overwrites the file if it exists, as determined by the hardcopy_append command. If the option -h is specified, dump also the contents of the scrollback buffer.

— Command: hardcopy_append state

(none)
If set to ‘on’, screen will append to the hardcopy.n files created by the command hardcopy; otherwise, these files are overwritten each time.

— Command: hardcopydir directory

(none)
Defines a directory where hardcopy files will be placed. If unset, hardcopys are dumped in screen's current working directory.
