Abstract
Abstract A daisy wheel printer print package including a daisy wheel print element and a cartridge. The cartridge is adapted to have the print element inserted thereinto and maintained in a latched and properly oriented position for either acceptance by a printer or storage and shipping. When the package is installed in a printer, the print element is adapted to be unlatched for rotation within the cartridge for printing. Also, the cartridge is adapted to have the print element unlatched and removed therefrom.
