Windows 10: can't find shared printer located on win 7 host computer

I have a cannon d300 printer on a win 7 host computer. I am trying to connect a win 10 lap top to it. The laptop sees the printer but will not cause it to print. Troubleshooter says no issue found

Can't share printer—getting error message

Step 1: Go to store.
Step 2: Buy a less shitty printer.
Step 3: Pick up some beer while you are there.
Step 4: Enjoy both your new printer and your beer.

In all seriousness, I have had more issues with Lexmark printers and their shitty drivers then any other manufacturer, HP is a close second though.

However, if you don't want to get a new printer*Laugh :laugh:, and I can understand that, when my Lexmark was giving me the same troubles in Win7(and Vista) I had to make sure the Windows firewall was ON and the firewall service was enabled and running. After I shared it I could re-disable the firewall and firewall services.

 

Can't share printer—getting error message

Ok, I'm going to take this one step further... I moved the printer to my server (thoroughbred) and it will handle the printing from now on. Now I won't have printer drivers on my gaming machine...

I'm a bit worried about sharing it between a 32-bit xp system and a 64-bit 7 system, though

 

Network-Shared Printer: Remote Printing changes default printer on *host*

Problem Description (encountered multiple times at several customers' networks):

Although the "Let Windows manage default printer" ist disabled (HKCU\\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows LegacyDefaultPrinterMode set to 1), the default printer on a hosting win 10 pc is getting changed as soon as another remote win10-host
is printing to that shared printer.

For example:

An arbitrary USB printer is attached to host A and shared via local network.

Additionally, another printer is attached to host A and is the system's default printer (and is supposed to stay like that!).

Now when a user starts printing on host B to the shared printer on host A, the default printer on *host A* is getting changed to the shared printer instead of the other one.

Is this an already known bug in Win 10 (Build 1511 btw.)? Are there any known workarounds?
