Hi Some more Ideas for SOC:
Printer-Dialogs: PrintDlgEx* is the Default Printing-Dialog since w2k, but we have only a stub. Some Apps fail to Print for that reason. A usable Implementation need to Support the Properties from the Application (Example from IE: Print actual Frame / Print Links only) and the Properties from the Printer-Driver (provided by wineps.drv from the PPD-File).
Fun-Project: Support Native Printer Drivers The CUPS-Backend "ddiwrapper" (GPL) uses Ghostscript to render BMP-Images on Linux, forward them to an modified wine (winspool.drv and gdi32.dll are replaced) that used a native driver (reported to work with some Cannon-Printers) to print that BMP-Image to the Printer (/dev/lp0 or /dev/usb/lp0). A usable Implementation will enhance winspool.dev and gdi32.dll in such a way, that "ddiwrapper" will work "out of the box"
Fun-Project: Support Native Scanner Drivers A usable Implementation will work with a modified twain_32.dll (and kernel32.dll / ntdll.dll), but without a Kernel-Module (Example: via libusb).
