Using the Tested Printer Guide Environmental Systems Research Institute (ESRI ® ) has assigned several support levels to define and document the functionality of various devices in their ability to work successfully with ArcGIS ® 8x, ArcInfo Workstation 8x, and ArcView GIS ® 3x. System configurations, connections, and peripherals can all contribute to the success or failure of any device with ArcGIS ® 8x, ArcInfo Workstation 8x, and ArcView GIS. Tested printers ESRI supports Ethernet and direct connection of printers and plotters to a computer workstation or server via an RS-232 or parallel interface. The user is responsible for connecting and establishing communications between the printer and the host. The ratings for the following listed devices are based on their ability to correctly interpret and render graphics using ArcGIS ® 8x, ArcInfo Workstation 8x, and ArcView GIS ® 3x output formats. Each device was tested using the most current released firmware available at the time. PostScript (.eps, .ps) and Enhanced Windows Metafile (.emf) are supported by ArcGIS ® 8x, ArcInfo Workstation 8x, and ArcView GIS ® 3x software. Because these formats are supported on a wide variety of desktop and large format printers, ESRI has not listed each and every supported printer. If you are unsure whether a specific printer will support these formats, check the ‘Standard Printer Input Formats’ listed for each printer in the Printer Specifications section or your printer manufacturer’s documentation.
