Epson FX-850/850+/1050/1050+
The Epson FX-850/1050 9 pin dot matrix printers were launched in August 1988 to replace the FX-800/1000 series. They offered greatly improved print speed, paper handling - including paper parking and microfeed - and lower noise levels than their predecessors. Each printer has two sets of DIP (Dual In-line Package) switches located on the right-hand side panel of the printer. These switches control certain printer functions and default settings, the details of which are listed below.
