Question

I’m trying to create some xlsx files using the Apache POI library for Java and everything to create the files is working fine.

The problem comes when I want to print those files using a physical printer. I want to make each sheet in my workbooks fit to a single page. I looked around in the documentation and the following code would be supposed to work:

       XSSFWorkbook wb = new XSSFWorkbook();
       XSSFSheet sheet = wb.createSheet("format sheet");

       PrintSetup ps = sheet.getPrintSetup();

       sheet.setAutobreaks(true);

       ps.setFitHeight((short)1);
       ps.setFitWidth((short)1);

       for(int i = 0; i < 100; ++i){
            sheet.createRow(i);
            sheet.getRow(i).createCell(0).setCellValue("Test " + i);
        }

       FileOutputStream output = new FileOutputStream("Test.xlsx");
       wb.write(output);
       output.close();

But it doesn’t… When I try to print it, it prints to three sheets (what it would actually be supposed to print on if I didn’t use the PrintSetup part). So the code just doesn’t do anything at all.

Can anyone tell me what is wrong with that code?

Also, I have another question about printing xlsx files: I want to know if there’s a way to print the xlsx files from my Java program without actually opening the files and clicking on print? Like wb.printAllSheetsInWorkbook(); or something like that.

Answer 1

After

ps.setFitHeight((short)1);
ps.setFitWidth((short)1);

Use

sheet.setFitToPage(true);
