Etaf, Thanks for your help.
I went to your link and found How-to Geek and then the hopeful sentence Today we show you how to share a printer from either Vista or XP to Windows 7. Unfortunately I believe this solution DOES NOT WORK for many users. It DID NOT WORK for me, but it was helpful although possibly not necessary. I had tried the steps suggested previously, but when I retried them my xp Desktop printer was found for the first time on my network as displayed on my Netbook. However, when trying to connect to the printer I got an access denied message.
Searching for wireless printing access denied on Tech Support Guy lead me to a post by a user named melonhead. Look for his post on 11-Feb-2007 7:11 PM. It worked for me and for several others who had sent email thanks to melonhead.
Melonheads solution was for Vista. The main idea is that you need to add a local printer and when asked for a port type \\computer Name\printer name. (Computer name is the name of the xp computer, and the printer name is the name of the printer on the xp, in my case Printer5.
Here is what I did on System 7. I clicked Start, then selected Devices and Printers. On next screen selected Add a printer. On next screen selected Add a local printer. On next screen selected create a new port, left Local port as the port type, and clicked next. I was prompted for port name and entered \\OFFICEXP\Printer5. I was then prompted to install a driver. I choose the HP5550 which installed from the internet. There were a few more choices (nothing hard) including selecting this printer as the default printer.
Thanks again for your response, I would not have made progress without it. If you want to explore this further please contact me, meanwhile I am happy to consider this wireless printing problem as solved.
