COR Action 2 (IDB Option 124) This SCS Options > COR/APO Settings option defines how the APO/COR function (Automatic Page Orientation/Computer Output Reduction) works for paper tray 2 and above. With this option it is possible to disable the APO/COR function so that the page orientation change only can be made manually. It is also possible to select between Landscape and Portrait (APO) only, or it can be stated that automatic reduction (COR) is performed after the APO as well. Refer to "Appendix D - COR/APO Logic (TN5250e)" on page 287. When Enable APO is selected, the SCS/TNe Emulation calculates the print area required for printing the document. If the document does not fit on the page in portrait orientation, the orientation is changed to landscape. The Enable Auto COR function is an extension of the Enable APO function. If the page does not fit after the APO has been performed, the COR function is activated. This is done using the CPI compressions specified with the Compress CPI (IDB Option 128) option. If the page cannot be made to fit, the setting of the Def Page Ori 2 (IDB Option 122) option is used together with the compressed CPI.
