Hans, I have the following sample: \setuppapersize[A5][A4, landscape] \setuparranging[2SIDE] \setuplayout [backspace=0pt, topspace=0pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \setupinteractionscreen[option=paper, copies=5] \startbuffer[a] \showframe \setuppapersize[A5] \setuppagenumbering[location=] \setuplayout[width=middle] \starttext \mbox{}\vfill \startalign[middle] \dontleavehmode \framedtext[width=10cm, align={lohi, center}, foregroundstyle=\ssbfb] {Just \tex{typesetbuffer}} \stopalign\vfill \stoptext \stopbuffer \startbuffer[b] \showframe \setuppapersize[A5] \setuppagenumbering[location=] \setuplayout[width=middle] \starttext \mbox{}\vfill \startalign[middle] \dontleavehmode \framedtext[width=10cm, align={lohi, center}, foregroundstyle=\ssbfb] {Just another \tex{typesetbuffer}} \stopalign\vfill \stoptext \stopbuffer \startbuffer[c] \showframe \setuppapersize[A5] \setuppagenumbering[location=] \setuplayout[width=middle] \starttext \mbox{}\vfill \startalign[middle] \dontleavehmode \framedtext[width=10cm, align={lohi, center}, foregroundstyle=\ssbfb] {And even another \tex{typesetbuffer}} \stopalign\vfill \stoptext \stopbuffer \starttext \startmakeup[standard][style=\ssbfb, align=middle] Just an empty page. \stopmakeup \typesetbuffer[a] \typesetbuffer[b] \typesetbuffer[c] \stoptext It contains three buffers. In 2013 (https://mailman.ntg.nl/pipermail/ntg-context/2013/075894.html), you implemented a method to avoid renewed \typesetbuffer compilation, if buffer and PDF document hadn’t been changed (by ckeching their MD5 checksums) and PDF document has been generated. Now \typesetbuffer compiles the document every time the main document is compiled (no matter whether the buffer or the PDF document haven’t been modified). Also the same fonts were embedded only once (as far as I can remember) and now they are embedded multiple times. Could you check the issues? Many thanks for your help, Pablo -- http://www.ousia.tk
