-	Let's not use samba printing because ~~samba uses lpr anyways~~ and windows actually includes a good lpr for printing to a lpd. This way we remove a layer which make it less complex and therefore easier to understand. Also, it works well. The idea is to pass through without filters (which otherwise are a convenience feature for unix printing) data from the windows printer driver to the USB printer via lpd. lpd listens on port 515 for data requesting print jobs and then jumps into action. It forwards data to the printer and also does accounting which I do not really need.	+	Let's not use samba printing because it just adds complexity and windows actually includes a good lpr for printing to a lpd.

		+	=== 10) raw printing, cups ===
		+
		+	Since lprng also supports "raw" printing using port 9100 ("socket") as a special queue (?), it seems it might be possible to use the standard tcp/ip port in windows and avoid lpd/lpr print services enabling. Something to keep in mind in case MS gets rid but not worth changing if the setup is working.
		+
		+	cups would be interesting for "driverless" printing (eg. google cloud printing) since then cups would provide its own driver. It can be installed with optware quite straightforwardly. However, not all printers have cups drivers, especially under arm. In particular the Canon Imageclass MF4350d printer is not supported at all since Canon uses there its proprietary UFRII language for which it only provides binary x86 drivers.
