Visual Basic Code printing bold text direct on the printer.

Visual Basic Code printing bold text direct on the printer.

This will be done through the escape Code sequence set by the printer manufacture. You must have a copy or manual of your printer for you to know the escape code sequence supported by your printer.

Dot matrix printers vary on codes when it comes to escape code sequence.

I have some copy of codes here for NLQ printer’s version and I tried this codes works on EPSON dot matrix printers.

Here’s how:

Printer Escape Code:

[Esc]!char(n)

            [Esc] = char(27)

Where n,

0 = PICA mode

1 = Elite mode

4 = condensed mode

8 = emphasized mode

16 = double strike mode (bold)

17 = ELITE/double strike mode

20 = condensed/double strike

24 = emphasized/double strike mode

32 = enlarge mode

33 = ELITE/enlarge mode

36 = condensed/enlarge mode

40 = emphasized/enlarge mode

48 = double strike/enlarge

49 = ELITE/double strike/enlarged

52 = condense./double strike./enlarge

56 = emphasized./double strike./enlarge

To apply the command in your code:

Open “LPT1” for output as #1

            Print #1, “This was sent to printer – normal”

            Print #1, chr(27) & “!” & chr(16) & “This was sent to printer – bold” & chr(27) & “!” & chr(0)

Close #1

The code chr(27) & “!” & chr(16) = set the printer to double strike mode or bold.

The code chr(27) & “!” & chr(0) = set the printer to pica mode (normal mode).
