As to the second question, what is developer license : It is a kind of Royalty Free License. It can be run on any number of servers or computers with any number of users, it is licensed by per developer. Developer License is royalty free for runtime desktop redistribution. Developer License does cover the Server License.
Server License: It can be run on one server/computer with any number of users, it is licensed by per production server/computer (you needn't pay for development/test and backup servers), you will need to purchase a server license for each production server/computer you wish to run Server License on. Server License can be run Windows NT Server, Windows 2000 Server, Windows 2003 Server, Windows 2008 Server etc. server systems. After you purchased a server license for a server, all users on this server will able to use this product without any restrictions.
If you wish run our product (command line or SDK or COM) on lots of computers, you need purchase Developer License (Royalty Free License), once you purchased Developer License, you can run our product on any number of computers, you can also integrate our product with your application and distribute it with your own application royalty free.
However, if you run our product on one server only, the one server license will be enough for you, you may choose proper license according to how many computers that you will run our product on.
You may look at full license agreement from following page.
Say if you put it that we want to use the command-line version on up to 12 servers. Which is the appropriate license to use? The answer is that you'd better purchase Developer License.
This article mainly talks about the Doc-print software. From this article maybe you can know one or two about what are developer license and Server License. Hoping those information will be useful for you.
