Epson ET-2750

Epson ET-2750 on my LAN.

Epson has released printer drivers for Linux, but the drivers are not made for Arch Linux. I downloaded the drivers, and found the relevant .pdo files, but the USB install did not work as expected in CUPS.

On the tiny printer screen I saw a wifi option, entered the LAN password. Then I could visit the printer on a local tcp/ip address. From the web interface installing the printer was easy.

So don't mess with drivers, just use the wifi options.

Running Koala on Max

Koala is a nice tool for SASS, Less and JavaScript kompilation / testing. However if you try to run the program on a Mac you have to allow the program.

After installation find the program in your Programs folder. Then press 'control' and right-click on the program launcher icon. Now you are able to run the program.

After this the program will launch normally from the launchpad.
