A missing Content-Length header could also cause problems. Next, either enable debug level logging in nginx: error_log /var/log/nginx.error.log debug; or just use "nc -v -l 8080" on your server and have your "GPRS printer" connect to http://server:8080/1234.txt so you can check its request headers.
