cANON mp800 WON'T print

[rocker]

When I try to print, I get the message "printer is offline check cables etc." Cables are fine. Printer is on. USB cable goes from my PC direct to MP800.

I have a second computer which is networked to this(main)one.
Wiring is:
my PC(PC1)to hub
hub to PC2

From the other pc, can print no problem, so signal goes from PC2 to (hub then to )PC1 then thru USB cable to printer and away she goes. So the power is on and the USB cable is sound and the printer prints. Where to from here???
Help please.

I FIXED MY PROBLEM:
opened Printers and Faxes
Deleted the printer
Add printer ("installed" it again)
worked.

this caused PC2 to now not be able to find the printer

Printers and Faxes again
Selected the printer.
Right click menu,
Share this printer.
Followed prompts.

On PC2
Printers and Faxes
Right click menu,
Add a printer wizard
Select network printer. Followed prompts.
double click printer name
