Alarm printing without a PC
I used to believe that in order to print something, you need to install a printer driver on a OS, Even for a network printer. There are some walk-throughs on the Internet showing how to configure a direct printing port.
I've searching for a common protocol over TCP/IP that can make a printer print something. And the answer is YES, which means you don't have to install a printer driver and just write a common tool that hopefully works on most of the network printers.
This makes it possible to have a JACE controller send out alarm message directly to a network printer. Among all options, HP port 9100 (RAW, AppSocket, JetDriver ...) seems to be the simplest. However, there is no standard specification of this protocol. It has to be tested on each target model.
