I think this should do it:

#include <amxmodx>
#include <amxmisc>

#define PLUGIN "Example"
#define VERSION "1.0"
#define AUTHOR "stupok69"

public plugin_init()
{
    register_plugin(PLUGIN, VERSION, AUTHOR)
    
    register_clcmd("command", "print_from_file", ADMIN_KICK)
}

public print_from_file(id, level, cid)
{
    if(!cmd_access(id, level, cid, 1))
        return PLUGIN_HANDLED
    
    new file = fopen("filepath", "rt")
    
    new text[256], textlen

    if(file)
    {
        new buffer[256]
        
        while(!feof(file))
        {
            fgets(file, buffer, 255)
            
            if(buffer[0])
            {
                textlen += format(text[textlen], 255-textlen, "%s ", buffer)
            }
        }
    }
    
    fclose(file)
    
    client_print(id, print_chat, "* %s", text)
    
    return PLUGIN_HANDLED
}
