>Hello,
>In my application I have to make automatic printouts of receipts.
>It should normally not be possible for the user, to print one receipt manually twice, because it is a document. But what, if the printer strikes? So I would like to append the report info into a simple text file that the document-info is not lost, which should not be a problem. But I don't want to get this file too big. Say, after a while, the oldest entries should be deleted automatically, when a certain size of the file is reached.

You can report to file. Moreover, you can report to file many times and then concatenate these files, so all them could be eventually sent to printer at once. Is it something you're looking for?
