Cant print special characters like chr(164) or chr(165) on okidate microline
Hello Experts,
We are usingto an old vb6 App print labels,
it Works just fine so now we would like to enable to print special charactes like spanish "ñ" and others...
Can you send me an example on how to do this ?
Regards
here es a part of that vb6 code

i didn't see any font chosen in your code. try to find out which fonts your label printer supports and choose one which is able to print ansi character set (or ISO-8859 oe Windows codepage 1252). then you have to find out the sequence for the printer to change the font and add it to your code.
note, if your printer normally can be used as a printer in your windows environment, you also could try to set the default font by printer setup applet.

What should happen if you give the my_str function a value of 1.235? Currently, the value is truncated (=1.23) instead of rounded (=1.24).
I suspect there are also simplifications or refactorings that might be applied to your code. For instance, the my_str() function might be simplified as:
Private Function my_str(d, le)
my_str = Right(Space(le) & Format(d,"0.00"), le)
End Function
neither chr(164) nor chr(165) are Spanish characters
chr 164 is a tag sign (¤) and chr 165 is the yen currency symbol (¥) while ñ is chr 241 in the windows codepage.
from which system you get the data from?

I agree with the comments made by sarabande.
You need to establish which coded-character-set or Code Page you are using, or intending to use.
Bear in mind that most printers only support certain character sets.
Modern laser devices tend to support most international character sets (such as ISO-8859-1), but dot-matrix devices support far fewer sets, and also tend to use older emulations (printer languages) than those used with laser devices.
And even with Okidata Microline devices, the supported emulations and character sets will vary from device to device; for example, with the Microline 490/491 devices:
It is also quite likely that the emulation and character set cannot be changed programmatically - you'd probably have to change them via the printer's front panel buttons.

Hello
you are reading a txt file with an encoding X and want to print the same glyph you see in the txt file after printing. You need to a) define the encoding of the glyphs in the txt file, b) define and use a codepage (encoding) on the printer and c) replace the byte value of the incoming txt value for each 'extra' glyph (like the ~n) with the byte value of the glyph of the encoding of the printer.
See following example code pages which shows which glyph (char) is printed for which byte value for a defined code page:
If you tell us the encodding of the txt file and the code page and printer emulation (IBM or Epson ESC/P) you use, we may help buidling the mapping table.
I have done so for another OKI printer, dbase data and VB a long time ago.

YES, DansDadUK, you are right. The table I have posted is only the Epson language value selection table.
As it is a Oki Microline printer I assume it supports Epson ESC/P and IBM Proprinter printing language (as all the dot-matrix printers normaly do).
The question is still, which code page is the base of the txt file having the ñ char with byte value xy and which codepage will be used on the printer.
For example, if the code page of the printer is PC850:
then sending a byte value of 164 will print the glyph for the ñ.
If the code page of the printer is ISO-Latin-1 then you get another glyph printed.
So, as the question was on how to get the printer to print a ñ when getting byte value 164, the answer is to set the printer to code page 850 or use ESC/P to change the code page before printing.
As it is a Oki Microline printer I assume it supports Epson ESC/P and IBM Proprinter printing language (as all the dot-matrix printers normaly do).

aikimark, good remark on my_str function, I really dont know what the original programmer attemped but we will pay attention to that too... thank you.

Sara, This is a very old legacy App still working fine,,,, it is getting the data from a vpf9 database
then the visual foxpro database is using codepage 850 (default codepage of a "dos" shell) as shown by hjgode.
if we assume that the printer prints windows codepage 1252 by default, you could try to replace all occurrences of char 164 (what is a lower-case ñ in cp 850) in your strings by char 241 (ñ in cp 1252) and char 165 (Ñ in cp 850) by char 209 (Ñ in cp 1252) before printing the string.
