@stud0r ,
Please, attach the source PostScript file in order we can localize the issue.

This is all

            ByteArrayOutputStream pdfStream = new ByteArrayOutputStream();
            PsDocument document = new PsDocument(officeStream);
            boolean suppressErrors = false;
            PdfSaveOptions options = new PdfSaveOptions(suppressErrors);
            document.saveAsPdf(pdfStream, options);
