· The text extraction can be successful only if the printed document itself contains text information. If the document is an image, drawing, metafile, etc, the printer driver will not be able to extract any text.
· In some cases the printing application sends the text or parts of the text as glyphs. The glyphs codes cannot be converted back to character codes, and the text file will contain unreadable characters. Use the “Filter Junk Characters” option from the INI file if you want the driver to not save the glyphs to the text file.
· The coordinates of the beginning text are reported by the printing application. The coordinates of the end of the text is calculated by the driver, based on the resolution, font, and the actual characters in the text. A small variation of 1 to 5 pixels is normal.
· The coordinates of the text are saved as they are received from the printing application. Some applications, such as Quicken, change the coordinate system during printing. The part of the driver which generates the text output is not aware of this fact. In cases where the printing application changes the coordinate system, the coordinates saved to the text file may not be relative to the upper left corner of the image. There is no workaround for this issue.
· When printing contents of cells from Excel, the contents of the cells are not separated. Use the “Add Space” option from the INI file to instruct the printer driver to add an extra space after each text out command.
· Words cut in half. It is possible that the following line “Black Ice test” is extracted from a document by the Monochrome printer driver and is saved to the text file as “Black Ice test”. This issue is caused by the printing application, which sends the text as different commands. The printer driver is not aware if the text is “correct”, the text will be saved exactly how it is received from the printing application. This is most likely to happen with applications such as Word and Notepad, when for example one part of a word or sentence is using one font and another part of the text is using a different font, or a word was typed and then later edited. Disabling the “Add Space” option will solve most of these occurrences.
