WordPerfect print error "unable to initialize output device" when accessing WP via Remote Desktop

Symptoms

When accessing WordPerfect via Remote Desktop (RDP), an error is seen when printing, "Unable to initialize output device".

Cause

By default, WordPerfect attempts to initialize all available printers in the background when the print dialog is opened, however this operation may interfere with printing as many printers are remote in an RDP connection.

Resolution

Change the "Init All Printers In Background" setting within WordPerfect to Off (0).

These steps involve editing the Windows Registry. As such it is important to backup the registry before proceeding:
