my Samsung CLP-315 showed the orange LED

It [link] started doing so a couple of months ago. That was rather unspecific. The printer is usually attached to my Internet router. Of course, there is no standard way to check that printer's status using Smart Panel. Smart Panel on my OS X computer already got set up with an SCX-4623F, and I found no way to make it take notice the CLP-315. Finally I had start a Windows PC (and not just a VM), attach the printer, and install Samsung's printer software. First Smart Panel showed a paper jam, and told me to use the Troubleshooting Guide. Alright, I opened the printer on the backside – as I had done already quite a couple of times. No jammed paper found. The status changed to something like "printer is open". Closed it again. Opened it again. Closed it again. Warm up… – a configuration status got printed successfully. I'm amazed. Works again. Also after I attached it again to my Internet router.

printing from my droid (the Samsung Galaxy Tab 10.1) to my network printer (a Samsung CLP-315) using the Samsung MobilePrint app

wow, I'm amazed! who would have thought, printing from a droid is that easy?

my Mac now prints on the colour laser printer attached to the FRITZ!Box router

The Samsung CLP-315 gets accessed via "HP JetDirect". Yesterday I wasn't able to set it up as network printer and let it find the driver on Samsung's CD. Today I let Samsung's printer installation routine set up a local printer (which isn't actually installed), but at least the driver got installed somewhere on OS X, and then I could assign the right driver to the network printer configuration. Now I successfully printed my 1st page on my very own Mac.
Alright, alright, I admit it: I vaguely remember already having successfully attached my ex's (i.e. "-1") Mac Mini (which isn't officially hers ...) my FRITZ!Box ..., so I knew it would work sooner or later.
Now this is really a nice CUPS printer set up underneath!!!
I wished my openSuSE-11.1 computers would accept the CLP-315 driver as well!
Until then I only create PDF-s on them and print them via Windows or OS X.

I really love this set up: the laser printer attached via USB to my 7270, acting as a network printer.

AVM's description on how to attach a printer to the 7270 through USB was actually very helpful.
