Printer defaults don't hold

Printer: Canon PIXMA Ip3000
OS: XP Home. After setting Print preferences in Control Panel, Printer, to 1. Plain paper. 2. A4, Potrait. 3. Apply & OK the printer obeys. Once.
After that Plain paper becomes Env, and A4, Portrait becomes DL (an envelope size) and Landscape. To have to check the setting before each print is bore. Clicking the Default buttons does restore the Control Panel Defaults, again once. Canon recommended Uninstall and reinstall from the CD. Of course there was no fix. The driver is upto date. Does anyone have an idea?

Just a shot in the dark....

Is there a cannon control panel? A desktop icon, or a taskbar icon? If so it's setting might supersede the settings within Printers and Faxes.

 

Thanks Derek for the prompt reply. I opened the icon in Programs and followed all the Print advice which basically took me to Print prefs & page set ups as per that found in Printers & faxes. I entered my usual stuff and will now await my next printing session(s) to see what happens. I will advise.
Thanks again. Brian
