Re: Escape codes for printer control

Yes.
I've  not really use .lis files - But yes - A .lis file is a text file.

I am 99.999% certain that I am writing the correct escape charioteer into the 
ASCII file using:
    write ... char(27) ...

The problem is subsequently printing the ASCII text file which contains the 
escape character and control string.
The problem is that I cannot get the thing working even using DOS edit - I 
using this approach I know that I have the correct escape character and control 
string after checking the lower level HEX code.
I should be able to do this.
As such it is not a necessary requirement to create the escape character in the 
file using SQR .
Once I can get an ASCII text file to use embedded escape character and control 
string then I will have to do it from writing SQR.
However, I don't think that this is the case - Writing chr(27) look fine.

I am fairly sure that the issue relates to PostScript which uses a different 
escape character - However, I cannot get this to work either.

If you do find a solution please send let me know...

HP supplies all the escape codes - If you need this information let me know...
