Thanks, it did the job!

To delete a page size (form), follow these steps:

1. Click start button, then Control Panel, and finally View devices and printers.
2. Click a printer in the list (e.g. Bullzip PDF Printer), then click Print server properties.
3. Select the form and press Delete

Hello,

I want to remove custom page sizes which were generated automatically by ducoflow.

How am I supposed to do that?
