I suggest filing a bug for cairo and when I get time I will look at<br>
changing the PS output. For PS level 3 a type 3 image can be used which<br>
includes the mask with the image. There is already code in cairo for<br>
doing this but due to the way poppler uses cairo this code path does not<br>
get activated.<br>
<br></blockquote><div><br></div><div>Thanks Adrian,</div><div>I will certainly file a bug to cairo postscript component. We're on poppler mailing list here, prhaps you could provide any advice to poppler team on how to invoke that part of code that currently is not getting activated? </div>

I use pdftops and pdftocairo on my printservers, and a numer of other files fail to print on Ricoh printers with the same "xyshow" error, as mentioned in the bug. I hope we can debug it until it is fixed both in pdftops and in pdftocairo. We already made great progress. </div>
