Updated 2020: Switched to another Router some time ago, need to update some info.
Actually, I've been running OpenWrt for a while now, just now have some time to write some notes down.
Simply upload OpenWrt firmware using the firmware-upgrade page.
opkg update opkg install p910nd luci-app-p910nd kmod-usb-printer
Webinterface: Services > p910nd - Printer Server
Enable: Yes Device: /dev/usb/lp0 Interface: lan Port: 9100 Bidirectional mode: Yes
After playing around with various Adblockers on my mobile devices and PCs as well as the PiHole project, I found that there is actually a similar solution available for OpenWrt routers.
opkg update opkg install adblock luci-app-adblock libustream-mbedtls
opkg update opkg install ddns-scripts luci-app-ddns wget
~~~ opkg update opkg install mosquitto-nossl luci-app-mosquitto ~~~
