what is the best way to convert html to postscript? in java

what is the best way ( if there is any ) in 开发者_运维问答java to convert html with css2 support to postscript file ?

Are you on linux? If so your best bet might be to first convert to pdf, and then use the command line utilty pdf2ps. According to this question iText does html to pdf, although the CSS support may not be great.

I think your best bet is iText which is a java library with support for direct HTML to PDF translation.
