Abstract: A printer driver adapting to a plurality of models of printers includes a function management unit that determines an available function based on function information including a constraint on a print setting, a print setting unit that generates a print setting screen based on a determination result from the function controlling unit, and a drawing unit that generates print data in response to a request to print drawing data. The function management unit determines whether a print setting value set for the drawing data conforms to the constraint, when the drawing unit responds to the request to print the drawing data. The drawing unit generates print data based on the determination result from the function management unit.

Abstract: A set of files making up a plug-in that is to be added to a base printer driver is stored all together in a single plug-in storage file. While no plug-in is added, the plug-in storage file is kept empty. A file making up the printer driver and the plug-in storage file are included as printer driver configuration files, and are described in a file list in a driver information file. When the printer driver is copied to a client computer, the files making up the printer driver and the plug-in storage file are transferred, following the descriptions in the file list.

Abstract: An activated carbon for use as a polarized electrode is brought into contact with an organic compound which forms an azeotropic mixture with water, so that the activated carbon is impregnated with the organic compound. Then, the activated carbon impregnated with the organic compound is dried with heat to remove the azeotropic mixture of the organic compound and the water. The activated carbon is immersed in the organic compound to impregnate the activated carbon with the organic compound. Preferably, when the organic compound forms an azeotropic mixture with water, the azeotropic mixture contains 28 weight % of water or more. The organic compound preferably comprises at least one compound selected from the group consisting of benzene, chlorobenzene, ethyl acetate, methyl ethyl ketone, 1,4-dioxane, and methyl acetate, and more preferably comprises benzene.
