What registry keys are involved in controlling printer sharing permissions?

Printer sharing permissions are primarily controlled through the `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers` key (for printer-specific settings) and `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares` (for share-level permissions). Additionally, user rights assignments related to network access, found under `HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users`, can influence who can access shared printers. The `Everyone` group's permissions within the Shares key are particularly important.
