†Like the Epson FX-1050, this control code doubles the character width. Unlike the Epson FX-1050, however, this code does not double the inter-character spacing. The formulas for total character spacing are as follows:

Epson FX-1050 2(char + 1 dot + space)

Epson Emulation 2(char + 1 dot) + space

Example The following sample illustrates double wide character printing.
