This topic provides tips for solving some problems that you may have with displaying, editing, and printing equations.

Equation does not display properly

After you have imported an equation into a document, it may sometimes be displayed using the wrong fonts or sizes. Some possible causes are: you removed screen or printer fonts that are used by the equation. If a screen font is missing, the equation should print properly. If a printer font is missing, you must re-install it, the default printer has changed since the equation was created, and the fonts used by the equation are not available on the new default printer.

To fix this, you can either change the default printer (using the Windows Control Panel), install the fonts for the current default printer, or edit the equation and choose different fonts, Windows is choosing the wrong screen font or handling italics poorly. You can’t do anything about this, but it will not affect the printing of the document, or overall, equations will display more consistently if you use TrueType fonts or Adobe Type Manager.

Cannot edit equation in previous version of Corel WordPerfect

You cannot edit equations created in Equation Editor 8 or 9 in previous versions of WordPerfect Office programs. If you want to edit documents containing equations using earlier versions of WordPerfect Office, use the Corel WordPerfect 5.1 to 7 Equation Editor.

Equation does not print properly

Equation Editor comes with two special fonts for printing equations: Fences and MTExtra. In addition, Equation Editor’s Symbol font or a standard Windows Symbol font (such as the one that comes with Adobe Type Manager) is required. You can print equations on any type of printer provided these fonts are properly installed for your printer. Equation Editor supplies PostScript Type 1 fonts for PostScript printers and Adobe Type Manager, HP LaserJet (PCL) fonts for LaserJet printers, and TrueType fonts, which may be used for printing on various types of printers including dot-matrix and HP DeskJet models. When you install Equation Editor, the fonts you need are automatically installed for each printer you have installed in Windows.

Sometimes, due to any number of factors, fonts are not properly installed into Windows. You can usually correct the situation by re-installing the fonts.

Fonts not available for printer

Equation Editor’s fonts have to be installed separately for each printer/port combination you want to print equations on. If you get a “fonts not available on default printer” message, Equation Editor’s fonts have not been installed for the current default printer. The reason may be that you installed the default printer after installing Equation Editor. You can change the default printer to one for which Equation Editor’s fonts have been installed.

Changing the default printer

There is always a default printer chosen from among the printers you have installed in Windows. Your choice of default printer can affect what fonts are available to Equation Editor. To change the default printer, click the Printers icon in the Windows Control Panel.
