When I installed dopdf7 in Windows XP, the HP1020 printer does not work, only print test page. this is a shared printer connected to another computer, i used via network.
When I uninstall dopdf7 shared printer to work again correct.
The fault appeared, when I re-install dopdf7.
My English is not good, I hope everyone can understand.

Hello,
We have tried to reproduce the issue by using the same setup (a shared HP printer and a locally installed doPDF) but all the prints were successful for both the physical printer and doPDF. This situation may be just a compatibility issue unfortunately and we cannot do much about it in this case.
