print documents via web interface
This simple php code will allow to choose one or more documents and prints them using the local cups printer. There is also a possibility to select one of the locally installed printers.
There are some prerequesites as follows:
- install unoconv and openoffice/libreoffice (import filters are required)
- install calc, writer, impress, draw as required (import formats)
- local lpr printing programm and lpstat for list of installed printers are required
- upload is putting any non-pdf document in a local folder on the webserver for conversion this folder must be writable by PHP/apache
- copy this file to location accessible by apache
