Java printing is similar to printing passbooks.

Some time ago, a student ID card was printed as needed.

 

The requirement is very simple, that is, to print the specified content in the specified coordinate point.

 

In order to achieve this, we have done a lot of work, but fortunately, with the help of everyone, we finally achieved the desired function.

 

The Code is as follows:

The commented out part above can be released to view the effect. The default printer on the server used by this code can also be used as needed.
