11.3.19 Printer drivers
11.3.19.1 Updating printer drivers
In order to maintain performance, Crystal Reports queries the printer driver for each of the font elements
(font metrics), such as average character height, character width, height of the ascenders and
descenders, internal leading, and so on. A problem may develop if using an older printer driver that
does not return the font metrics accurately. If you are experiencing problems when printing (missing
fields, incorrect formatting, and so on), it is recommended that you obtain and install the most recently
updated drivers for your printer. In many cases, the newer printer drivers provide accurate font metrics
and any printing issues are quickly resolved.
11.3.19.2 Inconsistencies due to printer drivers
Inconsistencies may occur if different printer drivers are used to create and print your reports. These
inconsistencies are a result of the various methods that individual printer drivers use to measure text
metrics such as font size. When printed, text-based objects may be misaligned, truncated, or overprint
each other. Examples of text-based objects include string or character fields, text objects, memo fields,
numeric fields, and formula fields.
Problems such as these may arise when you have:
• Two identical printers, but each one is using a different printer driver.
• Two different printers using the same printer driver.
• Two different printers using different printer drivers.
• One printer driver that uses the TrueType font and a second printer driver that maps TrueType fonts
to PostScript fonts.
• Two identical printers using the same printer driver, but each one is printing from a different version
of Microsoft Windows.
• Two identical printers using the same printer driver, but the printer drivers are different versions.
• Two identical printers, two identical printer drivers, and two identical operating systems, but the
resolution of the video drivers is different.
Therefore, while a document using one printer driver may require six full lines to display a block of text:
