I've purchased VeryDOC HTMLPrint. With Windows XP works perfectly, but
with Windows 7 can't change paper orientation to landscape, always
prints in portrait mode.
My system: Windows 7 Home Premium, Internet Explorer 9, printer Canon
iP4200 connected via home network.
Please by following solutions to try again,
1. Please run htmlprint.exe with administrator right,
2. Please give Full Control permission to Everyone user account to your target printer,
We hoping above two solutions will helpful to you, please give them a try.
