title: what is the best way to print invoice in java
body: <p>in my desktop application (POS System). I used IText api for generating invoices and printing, but my printer thermal invoice printer don't support .pdf file. only supporting text file and .docx file. i use simple text file printer print whole invoice in long vertical single word line and don't auto cut page. I used .docx file which works good, i got print as i designed. but my program first open document in ms word then give me print. my code is:</p>
  
  <pre><code>try
  
       {
  
  
              FileOutputStream output = new FileOutputStream(FILE);

                      CTBody body = doc.getDocument().getBody();
                      if(!body.isSetSectPr()){
                      body.addNewSectPr();
                      }
  
                      CTSectPr section = body.getSectPr();
                      if(!section.isSetPgSz()){
                      section.addNewPgSz();
                      }
