Abstract: A method for controlling a resource sharing apparatus coupling least one input device to a first host is disclosed. A first input signal is acquired from the input device, and whether the first input signal comprises standby indication of a switching command is determined. The input device is disconnected from the first host when the first input signal comprises the standby indication, and the input device is emulated to the first host.

Abstract: A method for transforming a source image into a target image with the original resolution N time to the target resolution is disclosed. The original image data of pixels is read and stored for N scan lines and grouped into a series of matrices each including N2 pixels. The matrices are then classified into various matrix types defined previously, wherein matrices with different numbers of original dots are classified as different matrix types. The target image is formed with a plurality of target units each determined based on one corresponding matrix. In general, a target unit is drawn with target dots having a larger total area when its corresponding matrix includes a larger number of the original dots.

Abstract: A method for converting a facsimile-based vertical resolution to a printer-based vertical resolution is disclosed. The printer-based vertical resolution is firstly divided by using the facsimile-based vertical resolution to obtain a quotient and a remainder both being integers. All the data lines of the printing job are repeatedly generated for “quotient” times. Next, some data lines that their total number equals to the remainder are selected from the repeatedly data lines for further generated once than the other is. The selected data lines can be randomly or fixed selected from the data lines.
