Change printer sleep time

Background: Brother HL-2270DW printer configured with my Xubuntu 12.10 over my home network. Whenever it finishes printing something, the fan keeps running for about 2 hours before going to sleep.

Question: Is there any way I can decrease this "awake" time, so that the fan stops running sooner? For example, is there a configuration file I am able to edit?

So I found the answer at a Launchpad question from someone experiencing a similar problem. After somehow starting to search for a "ppd" file as a possible solution, I stumbled on said Launchpad question.

So when I installed the lpr and cups drivers from the Brother site, it created a ppd file at /usr/share/cups/model, with the name of my printer model. So I opened cups, navigated to Administration -> Manage Printers -> Brother_HL-2270DW_series -> Administration/Modify Printer, chose Brother as the make, and added the ppd file from said location. This installed the correct drivers, giving me full access to all printer features, including sleep time!

Found this on Ask Ubuntu. People say printer configuration (sleep time...) works well with Original Drivers
