FoxIt PDF Reader
The program FoxIt PDF Reader can be used als an alternative for Adobe Reader, it is a free program to view, create and print PDF files. FoxIt can be found on the S disk in the directory "FoxIt-PDF-Reader", which also contains a user manual in PDF format.
One reason to sometimes not use Adobe Reader is that Adobe Reader 8 produces PostScript that the HP4250/HP4350 printers can't handle, not even after a firmware upgrade. Therefore C&CZ switched to using the (slower) PCL-driver for almost all HP4250/HP4350 printers.
