Using the printer
One of the advantages of the Windows operating system is its built-in support
for a wide range of printers. ClearWin+ caters for three different types of
� Simple text output to the printer.
� HTML text output.
� Graphics output.
Before you can send output to the printer it is usually necessary to prompt the
user to select the printer to use (this also gives users the opportunity to
cancel the print request). There are several methods to obtain this information
each of which is described in the topics that follow.
The resolution of a printer varies from one machine to another, but typically
printers offer a much finer resolution than even a high quality graphics
driver. This means that screen images must be re-drawn for a printer after
determining the resolution of the printer selected by the user. If you are
using bitmap images as part of your printer output, you may need to use a
higher resolution image on the printer than on the screen.
If you send simple text to the printer it will look rather plain because a
single font will be used. However, this is sometimes useful for debugging
purposes. It is almost as easy to send HTML output to the printer, and this is
the recommended method for producing professional printed output from
