CUPs printing

Hi! I am having problems to print landscape Postscript files with the new CUPS system. Use a2ps -2 file1 -o file2.ps to generate a new PS file with landscape orientation, and it is rendered correctly in gv, but when printed, it was in the wrong orientation. There is no problem to print portrait PS files The OS is SuSE 8.1 , using CUPS . The printer is HP LaserJet 2100TN, using the configuration of HP LaserJet 2100M, and choose the driver "pxlmon". The same PS file was printed correctly from another PC with SuSE 7.3 , lprng system and ghostscript version 6.51 I am not sure whether it is the problem of CUPs or ghostscript, anybody has similar experiences? Thanks! Yongtao Yang yongtao.yang@telia.com
