Drawing not working well

[pythoncat1]

I created the version of the printerbot in the instructions and I noticed it is different to the one in the video. Upon testing with images/test.svg, the image doesn't turn out great and some letters are backwards. I was wondering how to fix this. Additionally, I am not sure which ports you meant in the instructions by Connect left touch sensor to port 2 and right touch sensor to port 3. as these instructions can be interpreted differently depending on whether you're looking at the EV3 brick up or down. Thanks!
