I have not problems with software. I use it 9 months. There is only one problem with printer - yellow white is very dirty and can't be remove by printer. I try to use EZ controller software and nothing help. This is my best condition - print in color and black and white. If someone need, in my cases ( it's not much ) can sell this version - include dongle. You can use it for free and if you not satisfied - email me to my email - email@example.com and send me proof for your order and I will resend you installed dongle.
