Main principle
- Prepare the sequence of operations…
Connection
- Once the command file is built, send it to vpxPrint.
- Click to see examples with different environments.
And beyond...
- Familiarize yourself with all the features.
- Learn how to draw pages, images, barcodes, send emails, create PDF files with “The Discovery”

1.import subprocess:
subprocess.call([“c:/windows/system32/vpxcall”, ‘C:/temp/python.xpr’])
2. call vpxCall:
param = ‘C:/temp/python.xpr’
arg=[“vpxCall”, param] # optional , “-LOG”
subprocess.Popen(arg)
3. call the dll:
xprint = cdll.LoadLibrary(“xprint.dll”)
xprint.printFile(‘C:/temp/python.xpr’)

The command file
The data and commands are inserted in a text file, with ANSI or UNICODE encoding, usually with a .xpr suffix.
The commands and options are specified in tags surrounded by < and >, such as in an HTML file. But fear not, their format is much simpler and the commands are concise and powerful.
Example:
… is a seed file that previews “Hello World!” on the screen and also creates a PDF file called C:\temp\hello.pdf with the same content.
Another example:
… builds in memory (
How many lines of code should you write for this without vpxPrint? How long would it take you?
But more than this, a multitude of situations are possible, printing of course but also archiving (multi-page TIF files), sending marketing emails, creating PDF files for remote printing …
Images, figures, lines, bar codes, draw on your canvas, manage Excel or Powerpoint, the limit is your imagination!
This file will then be rendered by vpxPrint in a Windows environment but the file can be built on any other environment.
vpxPrint is able to render local files, internet-intranet files from a web server or a FTP server.
