Ok heres the deal. HP 2100TN on Mac network, bitmap image at 1440 dpi 9 cm x 10cm in Photoshop 5.5 with the Laser Writer 8 software and the 2100 series PPD selected. Landscape paper orientation. The printer gives me an out of memory error. If i change the paper orientation back to portrait it prints fine. Why? It has printed most of these same images before without giving me problems in landscape mode. I've got to be missing something here but after dinking with it for a few hours im worn out.
