I have an HP LaserJet 4200N printer connected to a LAN and in use by a mix of twenty PCs and Macs. As of lately, and from out of the blue some pdf files will not print to the device. It is a completely weird problem, not all pdfs, but some. The affected docs are printed from a web-site running the "BlackBoard" educational suite, and are scanned from text-books. The web browsers in use are Mozilla Firefox 2 and Internet Explorer 7.
What happens is that the document is loaded into the browser but expands to around 2000% it actual size, which comes to around five hundred MB. This seems to fill the buffer and crashes the whole process. A limited workaround is to print the image as a .tiff instead of a .pdf.
