I create numerous pdfs in Acrobat Pro 9 (Windows XP, Office 2007). After inserting a document with several Excel charts, sometimes one chart will show and another will not on the same page. These are very small charts. This time I had to recreate the chart in order for it to show in the pdf, but that's not always possible if all the data labels aren't showing. Any suggestions? Show large images is already checked. It also happens sometimes when there is a bmp in the header on a page.
I believe what you're experiencing is related to this known issue Some characters in textbox lost when you convert PDFs in Excel 2007 (Acrobat 9), which is related to an Excel printing problem.
