1- it takes time... not a lot but slower than any regular POS
2.-I have a hard time controlling how it prints. I need to do a lot of tinkering with the fonts and everything to get right. The paper length how ever has not been resolved at all. It will print just the items at the top and then eject a long roll of paper.
I am looking for somebody who has either experience with POS thermal printers, Firefox plug-ins etc.
Make sure the first word of your response is FF43
Also there is no need to give me websites you have worked on as I don't care this is a project about printing and firefox.
