The program FoxIt PDF Reader can be used as an alternative to Adobe Reader, it is a free program to view or print PDF files.

One reason to sometimes not use Adobe Reader is that Adobe Reader 8 produces PostScript that 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.
