Abstract: A method, system, and computer program product for transparently loading resources (such as stored bitmaps, images, fonts, and sound files) from read-only memory ("ROM") for an application program executing on a Java virtual machine ("JVM"). Typically, the invention will be used on an embedded computing device which has no disk storage and no file system software. A novel class loader is described, which loads resources from ROM  and returns an input stream object as is expected by the existing application program.  Therefore, when using the present invention, no change is required to existing application code to use resources stored in ROM. (In addition, no change to existing applications is required in order to invoke the code of the present invention.) The invention may be used with programs written in the Java programming language, or with programs written in other languages that execute on a JVM.

Abstract: The invention relates to a method and a device to control a paper drive- mechanism (8) which is devoid of a sprocket feed in an electrographic printer that outputs data on a pre-printed striplike recording medium (5). Said recording medium (5) has th e same optical marking (109) on all pages. In a start operation, the front edge (110) of th e recording medium (5) is inputted into an input zone (69) at a specific insert mark (65a), whereupon said recording medium (5) is conveyed by means of a conveyor motor (41, 102) in direction ( A) at a given length and at a first relatively low speed. A sensor (59,85) scans a specifi c area of the recording medium (5) during the conveyance process and transmits scanning signals to an evaluation device (100). The evaluation device (100) examines whether the scanning signals coincide with the marking characteristics (109) and the length of conveyance between two similar successive markings (109) is identified by the evaluation device (10 0) as a page length value. The printing process is initiated at a second relatively high speed o f conveyance and conveyance is controlled according to the identified page length value.</SDO AB>
