Printing documents of non-standard paper sizes inside the Viewer can sometimes give you unwanted results such as cropping of pages or some empty spaces at the bottom of the printing area. Let's look at why such problems may occur and the printing workflow you should use inside the Viewer in order to eliminate those issues and achieve the best printing results. Printing a document in the Viewer is a two-step process which differs from a standard printing scenario that you might see in some desktop applications. This section discusses why this two-step process is required.

No matter what format your document is in currently, in order to display it in the browser it has to be converted into SVG format. The caveat of using SVG is that it's scalable and doesn't have a fixed width or height properties embedded into it (for example, like the PNG image). That's why in order to print it correctly we need to apply a specific size before sending it to the printing tool that is part of your browser. Let's look at how this can be done.

Step 1: Forcing a specific print size

1. Open a document of choice inside the Viewer.
2. Click Print and the Print dialog displays:

3. Select the printing options that you need. The first page of the document will print in portrait orientation using A4 paper size. (That’s where we force the SVG content to be a specific printing size).
4. Click Print and this information is sent to the browser’s printing middleware.

Step 2: Sync browser printing settings

The Print Preview dialog is a part of the browser and will differ depending on what browser you use. The following example uses Google Chrome.

1. Once all of the printing data has been loaded, a Print Preview dialog displays the default options:

2. Since you already selected the print settings in Step 1 above, now you need to make sure that the browser print settings are the same. Click on More Settings.
3. The list of options is similar to the Viewer Print dialog. Select the A4 paper size from the drop-down:

4. The non-standard paper sizes should now print correctly.
