I cannot print web page, i.e. confirmation of reservation of rental car on price line, yet I can print E-Mails, etc.

I need more information, please.

From the Network page you want to print, using either the drop down menu under the printer Icon or the File> Page Setup | File> Print Preview can you see the image that is supposed to print?

Using the Icon drop down or the File>Print drop down, can you verify that the correct printer is selected?
