Duplex printing with 2 different files

[Jose Luis S. Teixeira]

Hi,

I have a problem...

Description:
In my intranet i need to print hundreds of files in duplex:
    - front side an file in HTML
    - back side an PRN or DWG/DXF file

I thinked to try the following:
    - My progammer skills are not so high... :(
    - convert the html to ps then
    - convert the prn/dwg to ps
    - concatenate the two files into one ps file
    - convert the final ps file into pdf

I already see utility that convert HTML2PS, PS2PDF is there other utilities
for the rest of the process?

Any ideas are welcome!!!!


P.S. Sorry my BAD english
