In all the SCADA systems that I have ever done, I have always spec'ed a Dot matrix printer for Alarm Printing. Using a Dot matrix it is simple for the printer to do line by line printing and not form feed a whole sheet of paper.
With the price of Dot matrix printers going up and Ink/Bubble/Laser Jet printers going down. Has anyone been able to use one of these types of printers for alarm printing, and not have it form feed a sheet of paper for every alarm it prints?
