I cannot reproduce this. Which version of winspool.drv do you have?
@lhg19202212 Hi, I'm also having this problem. Some of the GDI hooks I did work, some of them not, and none of the winspool.drv hooked functions work... How did you fixed this ?
@Bonjour123 see #17
@poizan42 You were right, I was convinced I had the last version, but actually no. Thanks !
