How to hide the Form Feed char in JTextArea

Question

We have reports (written in C) that are being displayed in a JTextArea.
In our old app, the Form Feed character (ASCII 12) was invisible naturally without having to code around it. In a JTextArea, it appears as a "[]" character. Does anyone know how to make this character invisible to the JTextArea? Removing it is not an option, as it is needed for it's print routine.
I've been searching these forums and the web all morning with no luck.

Answer 1

Not sure how the Form Feed character worksIt lets the printer know that a new page is to be started at that point.
Does it always appear with the New Line character?Usually but not always.
Thanks for the reply. It's more involved than just printing standard lines of text, so perhaps I should have been more clear.
The C report already has pagination built in from when it was run from our legacy GUI. In other words, each report knows how many chars wide and how many lines down each page will be. It is different for each report, but they all hover around 150 chars wide and 60 lines down per page, since they are all presented to the user (and printed) in landscape.
In the C code: at the end of each report line a "\n" is appended. At the end of each page, an ASCII 12 character is appended. A header is at the top of each page (different for each report, but usually 2 or 3 lines) that shows the page # and other info.
So, as you are viewing the report, you would see page 1 header, some report content, page 2 header, some more report content, page 3 header, etc. as you scroll down.
So now if you view it in Java: if the user wishes to print, the report is sent to our ReportPrinter class, who tokenizes the report based on "\f" and makes a ReportPage object (implements Printable) for each token. Each ReportPage is then appened to a java.awt.print.Book object, who in turn is sent to the PrinterJob.
Given that the report already has his pages figured out and has a form feed char at the end of each page, the report comes in to the JTextArea with [] chars preceding each page header (approximately every 60th line, depending on the report).
I tried using a JTextPane, but no luck. It was also much slower reading in the report. I just want the textpane to not display the non-printable characters ("\f" in this case).
