Description
➊
This code sequence switches the printer to double strike mode. In double strike mode
characters are printed in two printing passes at the same horizontal position; thus print
appears thicker and fuller. Print speed is reduced since the characters are printed
twice.
Double strike mode can be used in combination with emphasized mode (ESC E).
Double strike mode is reset when the printer receives the code sequence ESC H.
➋
This code sequence resets the double strike mode set by ESC G or ESC !.
This code sequence is ignored when the printer is not in double strike mode.

40 LPRINT CHR$(27);"G";
