Epson FX-80 Operation Manual page 148

In the Normal-density bit image mode, the maximum number of dot positions
printable per line is 480 (FX-80) or 816 (FX-lOO). Therefore, the values of nl and nz
specified in excess of 480 (FX-80) or 816 (FX-lOO) dot positions are ignored. Mixing
of text data and bit image data on the same line is possible.
When text data and bit-image data are mixed on a line, it is necessary to take into
account that the amount of printable bit-image data decreases due to print in Text
mode.
