+PRINTING SUPPORT
+
+Starting with version 4.6.1, Qt for OS/2 supports printing through the CUPS
+framework (provided that this support is enabled when building Qt, see the
+respective sections in the beginning of this document). The OS/2 implementation
+of the CUPS framework is provided by the eCUPS package available at
+http://svn.netlabs.org/ecups/.
+
+The Qt Runtime detects the presence of eCUPS in the system on the fly and talks
+to the CUPS daemon directly, bypassing the standard OS/2 printing subsystem.
+This means that in order to print from Qt applications, you don't need to create
+and configure printer objects using the standard OS/2 system printer setup
+procedure -- you only need to install eCUPS and configure your printers in
+there. Please refer to the eCUPS user manual to obtain the detailed instructions
+on how to configure CUPS printers.
