RetroPrinter Support

The latest version of the PrinterToPDF software appears on GItHub - https://github.com/RWAP/PrinterToPDF

This is the public domain (GPL) version of the conversion software used on the RetroPrinter and can be used to convert Epson printer (ESC/P and ESC/P2) files to PDF.

v1.2 Has been released today with improvements to the handling of the configuration parameters; and the use of libHaru (www.libharu.org) to do the PDF conversion.

We decided to switch to libHaru in order to improve the speed of PDF generation, and also to allow greater flexibility. For example, we would like to see ASCII data being printed direct to the PDF, allowing a wider range of fonts to be used and smoother text than is available from plotting the text as bitmap graphics.

v1.4 has now been released. This reflects changes to the Epson ESC/P2 convertor for the main Retro-Printer Module, including improved handling of line feed characters and 9 pin printing; and handling of extended control codes.

It also incorporates a read_byte_from_file function which attempts to read raw Epson data from 1.prn (you can change the filename to suit your requirements)

v1.6 of PrinterToPDF has now been released - this fixes some issues with compiling and file conversion

We have now released v1.6.4 of PrinterToPDF. Highlights are:

• Minor bug fix to the use of letter quality

• Improve read_byte_from_file()

• Improve comments on MSB Setting to clarify usage

• 8 bit characters are enabled by default (for international character sets for example)

• More page sizes added, including A4 with wider margins

• The name of the file to be converted can be passed on the command line as last argument

• Superscript and subscript output is improved

• Bug with unexpected infinite loop fixed

v1.7 of PrinterToPDF has now been released.

This incorporates some of the fonts we developed for the Retro-Printer module. It is now also easier to pass parameters you require to select page size, input file name etc
