Windows Printing System For Applications
DOS Printer Escape Sequences I select in the Configuration dialog always becomes Printfil.ini
At Configuration -> Standard -> Escape there's a listbox on top you can use to select the "emulation" ( printer type / language ) used by your own source program ( IBM, HP PCL, EPSON ESC/P, ... ).
When selecting one emulation in that listbox, Printfil automatically populates the grid below with the corresponding decimal values ( escape sequences ) used to recognize those "effects" ( Bold, Italic, Condensed, ... ) within the text and graphically reproduce them in GDI mode on any Windows printer, even if the real destination printer does not natively support that emulation.
You can still manually add the "numbers" in the different rows of that grid, but the top selection is a faster way to configure the Printer Control Codes used by your own source program, if they're standard.
Once the values have been applied in that dialog they becomes part of the standard configuration (Printfil.ini), so if you enter that dialog again later on, the top selection will always show "Printfil.ini" instead of the emulation you selected previously (and eventually manually modified).
absolutely normal. The important thing is that the numbers in the grid
will match the sequences embedded by the source program into the print jobs.
If you'll change some sequence by mistake in the grid and want to revert back the changes, you can still select "Printfil.ini" in the top listbox to reload the last saved configuration, or you can click "Cancel" instead of "OK" to close the configuration dialog without saving the changes.
