If you wish to extract readable text from a PCL file, it is essential that symbol sets are specified correctly. EscapeE interprets the characters in the original document using the symbol set defined on the General page of the Configuration dialog. Note that changing the 'Source Type' will set up this symbol set automatically:
Source Type |
Typical symbolset |
Windows driver |
HP3 – the character codes are adjusted by 3 so that a "D" in the file is translated to "A", etc. |
RedTitan DDF (PrePrinter) |
none – no translation is required. |
RedTitan Datastream Converter |
9700 |
Other |
Custom PCL output usually requires no translation but a few drivers require symbol set HP-1 (adds 1 to each code). |
There are some printers which make the task of specifying the correct symbol set more onerous by creating their own ad hoc character codes. To resolve these issues, the RedTitan EEfonts program enables you to set up a custom character recognition database from EscapeE, see Character codes.
When EscapeE extracts and outputs text, it can be set up to use a different symbolset. You may choose to use the standard Windows character codes (19U), Unicode, or leave it Unchanged. |
Tip: You may change parameters on other pages of the Configuration dialog without closing the dialog. Just click Apply before you switch to another page, otherwise your changes on the Configuration page will be ignored. |
Changing the symbol set may affect any data-fields and tags set up previously. See Field Problems.
EscapeE may be set to recognize the symbolset automatically by selecting <Auto> from the 'symbol set' list. This feature may be requested on the command line using the option /SYMSET *
