[jira] [Comment Edited] (PDFBOX-3345) Treat
GraphicsDevice.TYPE_IMAGE_BUFFER as a printer
[ https://issues.apache.org/jira/browse/PDFBOX-3345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15276962#comment-15276962 ]

This would result in normal rendering being incorrect. You can see this with the page 1 of http://www.ghostscript.com/doc/examples/annots.pdf .
Also with PDFBOX-2203-019672.pdf, PDFBOX-2505-032618-p96.pdf, PDFBOX-2898.pdf
However I think your suggestion shows a problem: if we print using a non zero dpi parameter (which uses a buffer), then the FLAG_PRINTED would not be treated correctly.

> For our purposes we just decided to treat image buffer device as a regular printer, as it is shown in attached patch.
