Unable to send a Fax cover page when sending Fax from a computer

Issue description

Cover page is not being sent when selecting cover page.

Other observations when this issues occurs:

• PS UPD is used
• This is commonly seen on 64-bit Microsoft® Windows 10®
• This is commonly encountered when using 32-bit Microsoft Word®

Solution

To resolve this issue, update to the latest print driver version found on the Driver & downloads support site.

This driver creates the cover page from the driver code rather than depending on Microsoft's StartPage(hDC) api.

Explanation

Several factors lead up to this outcome:

• When cover page is enabled, the driver draws the cover page
• This adds an additional page to the print data.
• When drawing this additional page, it is dependent on the Microsoft core driver
• This requires the UPD to make GDI calls to create the additional page.
• Microsoft core driver generates postscript data based on these gdi calls
• However, when a driver makes a gdi start page call on Microsoft provided hDC (printer device context).
• An invalid handle error is returned when printing from 32 bit Word in 64 bit OS.
