If you're not satisfied with what you get, you can request refund.
If you're having issues, please file a detailed bug report. In particular, when it comes to MS Project export, it is almost always a good idea to send us a
.gan file and describe what is wrong with exported MS Project file.
The best and recommended way to print is to export (Project->Export) to PNG or PDF and print the result using appropriate printing tools.
Hope it helps.
