Francis- With the OpenOffice transparency phenomenon, that indicates to me that perhaps they are using X-server pixmaps to do the preparation of the print job? I wonder happens if you are running the terminal in 8-bit mode? Does that mean that your prints will be limited to 256 colors or less?
I say this because some time ago I was helping with the DigiKam project on their photo printing code, and I mistakenly used the QPixmap to build the printed photos before I realized that it was "dumbing down" the photos to whatever bit depth I was running at the time. So if I was running 16-bit, I could never create a 24/32-bit pixmap. I never checked the memory usage, but I'm sure it was high. I switched the code to use server-side in-memory images, which is what it sounds like OOo needs to do, especially if the printed output depends on the bit depth of the terminal. -Todd Francis Giraldeau wrote: > Hi, > > With linux terminals (like LTSP) the memory used by the X server is > realy an issue, because it can (and will) crash the terminal.
