It seems to me that converting that parallel data to serial would turn the handshaking to be performed in hardware, so it will be fast, and I would not loose (synchronization) strobes and bytes consequently. Additionally I could be helped by the serial port buffer. About the PDF Writer, I don't know if I understand your suggestion, but I would need to configure a printer like I do in my computer, isn't it? The problem is that the equipment is "closed", it just sends ascii data to a printer. []s Rodrigo -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
