4. EPSON LQ-850 Printers
Early versions of the LQ-850 do not support the [Esc]+ sequence required for 360x360 dpi printing. This resulted in
printout that had double spaced lines of graphics terminated by backslashes. This is purely a software problem and
there is no mechanical reason for the printer not being able to support this resolution.
A ROM change to the printer will solve the problem. To establish which version of the ROM the printer has, a self
test should be run by turning the printer on with the Form Feed button held down. The ROM number will be printed
in the top left. If it is not one of the three following then an upgrade will be required.
