If your backend filter name is "filewriter", then the device URI (used in the lpadmin command) needs also to use "filewriter". You used "filewrite" (missing "r").

Keep in mind that the script is just a very simple sample to show how the thing basically works.

In a security-sensitive environment you may want to change a few things (most important: add some input validation, change the logfile path, ....)
