The alternatives 64/16 and 32/16 gave me a floating point exception just after selecting the printer type and pressing OK. Stack dump at the end of this message. None of the 64/4 or 32/4 looked good, but I've put them up at http://home.swipnet.se/consultron/scan3.jpg (56 kB) if they might give you some information. > I made a change to the softweave code that will affect all of the > older Epson printers (no variable dot size) in softweave mode. > Specifically, the sequence I was using (which worked on the EX) didn't > work on some other printers (the 800, most notably).

Downloaded and tried it and the change works OK - i.e. I do no longer get paper feeds (STC800), just striped output. :) The stack dump for 64/16 and 32/16 with the latest mainline: /usr/local/lib/gimp/1.1/plug-ins/print: Floating point exception caught /usr/local/lib/gimp/1.1/plug-ins/print (pid:2140): [E]xit, [H]alt, show [S]tacktrace or [P]roceed: s #0 0x401cf780 in g_on_error_stack_trace ( #1 0x401cf67d in g_on_error_query ( #2 0x4004cf14 in gimp_signal (signum=8) at gimp.c:1171 #3 0x402d8b18 in __restore () #4 0x80641d9 in plist_callback (widget=0x0, data=0) at print.c:2448 #5 0x8064c1f in setup_ok_callback () at print.c:2678 #6 0x400f165d in gtk_marshal_NONE__NONE (object=0x8107090, #7 0x40122155 in gtk_handlers_run (handlers=0x810d190, signal=0xbfffe940, #8 0x401214a0 in gtk_signal_real_emit (object=0x8107090, signal_id=79, #9 0x4011f3f1 in gtk_signal_emit (object=0x8107090, signal_id=79) #10 0x4008b5e8 in gtk_button_clicked (button=0x8107090) at gtkbutton.c:338 #11 0x4008cd48 in gtk_real_button_released (button=0x8107090) #12 0x400f165d in gtk_marshal_NONE__NONE (object=0x8107090, #13 0x40121343 in gtk_signal_real_emit (object=0x8107090, signal_id=78, #14 0x4011f3f1 in gtk_signal_emit (object=0x8107090, signal_id=78) #15 0x4008b528 in gtk_button_released (button=0x8107090) at gtkbutton.c:329 #16 0x4008c6a2 in gtk_button_button_release (widget=0x8107090, event=0x812b8e0) #17 0x400f1229 in gtk_marshal_BOOL__POINTER (object=0x8107090, #18 0x401214d9 in gtk_signal_real_emit (object=0x8107090, signal_id=21, #19 0x4011f3f1 in gtk_signal_emit (object=0x8107090, signal_id=21) #20 0x40157f58 in gtk_widget_event (widget=0x8107090, event=0x812b8e0) #21 0x400f1182 in gtk_propagate_event (widget=0x8107090, event=0x812b8e0) #22 0x400f02fa in gtk_main_do_event (event=0x812b8e0) at gtkmain.c:770 #23 0x401a3e5b in gdk_event_dispatch (source_data=0x0, #24 0x401d3673 in g_main_dispatch (current_time=0xbffff39c) at gmain.c:656 #25 0x401d3cab in g_main_iterate (block=1, dispatch=1) at gmain.c:874 #26 0x401d3e61 in g_main_run (loop=0x812ad58) at gmain.c:932 #27 0x400efbdb in gtk_main () at gtkmain.c:476 #28 0x80621c7 in do_print_dialog () at print.c:1670 #29 0x805e2e3 in run (name=0x80d2748 "file_print", nparams=3, param=0x80d2758, #30 0x4004d2d9 in gimp_proc_run (proc_run=0x80d2738) at gimp.c:1375 #31 0x4004d109 in gimp_loop () at gimp.c:1268 #32 0x4004bcaa in gimp_main (argc=6, argv=0xbffff5e4) at gimp.c:257 #33 0x805e160 in main (argc=6, argv=0xbffff5e4) at print.c:342 |
