Appeal No. 2001-2579 Page 2 Application No. 08/885,996 The printer includes a memory and a central processing unit ("CPU") for processing and printing the data. More specifically, the CPU features forms for storing the data in the memory, viz., a byte form, a word form, a long word form. For forms of two-byte data, "there are a high order type and a low order type." (Spec. at 2.) Because the print driver depends on the characteristics of the printer's CPU, explains the appellant, a different print driver must be used for each model of printer. (Id. at 3.) "This imposes burden[s] on both the user and the manufacturer. That is, the user must install the print driver with respect to each printer model and the printer manufacturer has maintenance difficulties."1 (Id.) In contrast, the appellant asserts that his invention enables a single print driver in a computer to support more than one model of printer. (Id. at 9.) More specifically, the print driver confirms the form of a printer's CPU, generates print data corresponding to the form, and transmits the print data to the printer. (Id. at 4.) Accordingly, concludes the appellant, a user of his invention need not install a different print driver for each model of printer, "and the printer manufacturer simplifies maintenance." (Id. at 9.) 1The "maintenance difficulties" are unspecified.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
