[Samba] I can not print with my network-printer

[serando]

Hello,

I have a desktop PC with MX Linux 64bit (Debian 10 based). My printer is 
connected via usb-cable with this PC.
On this PC I run also virtualbox with a "windows 7" VM (32bit).

My goal:
---------
When my "windows 7 VM" is running, I want to use the printer from Linux.


What I have done:
-----------------------
SAMBA:
Here are my SAMBA settings. (Please click the link. It will lead you to 
a gif- animation):

VirtualBox:
-Oracle VM VirtualBox Manager-> File-> host-only network manager-> create
-activated DHCP-Server
-Oracle VM VirtualBox Manager-> Machine-> change-> network-> Tab adapter 
1-> activate host-only adapter



There are 3 issues:
----------------------------------------------------------------------

Issue 1: I start the windows 7 VM. I start the file manager. I click the 
"network" folder. So sometimes I have under "network" a folder that 
contains all the printers from the host (and also the PDF folder). 
Sometimes I have both not. So I then restart the VM and when I have 
luck, then I have them after the restart. So sometimes I have them, but 
sometimes not.

Issue 2: I start the VM. I start the file manager. I click the "network" 
folder. I make sure that the printers and the PDF folder appear there. I 
click the "PDF" folder. I try to rename one of the files in the PDF folder.
Message: \Mx\pdf could not be accessed. You do not have permission to 
access \Mx\pdf. Contact the network administrator to request access.

Issue 3: I start the VM. I start the file manager. I click the "network" 
folder. I make sure that the printers appear there.
I open "Control Panel\Hardware and Sound\Devices and Printers" and press 
the button "add printer". After: "Add network printer". This way I get a 
list with all my printers from the host. I select the one I want. 
Message: No driver found. So: I'll grab the driver from the CD. I now 
have the printer in windows 7. For example also in Wordpad. So it looks 
all is how it should be. But now, I open Wordpad select this new printer 
and try to print. But the print get stuck in the windows print-queue:

Nothing goes out to the host. It does not print:


Question:
What am I doing wrong?

Would appreciate some help.
Thank you.
