You can do this with pdf files using the command line tool pdftk using the stamp or background option.
e.g.
$ pdftk file1.pdf background file2.pdf output combinedfile.pdf
This will only work with a one-page background file. If you have multiple pages, you can use the multibackground command instead.

Suspecting the drive was not being properly recognized as fixed, I checked the indexing locations again under Indexing Options, recalling that I kept seeing a folder displayed with a long ID string, and a tooltip informing me that that particular location was unavailable. I never assumed this to be a problem since I also have USB drives plugged in/out sometimes:
PROBLEM FIX: to set the drive to be seen by windows as permanently fixed follow Microsoft's own guide here: https://support.microsoft.com/en-us/help/3083627/internal-sata-drives-show-up-as-removeable-media
If for whatever reason the command mentioned in the MS guide doesn't work follow these steps below
it should look like this once you are done: 
reboot and check Indexing Options again, you should now see your drive on the selection list.

南天PR2E打印机支持OKI，IBM，LQ，Olivetti等多种仿真模式，其中OKI速度快兼容好，推荐使用OKI仿真。
【PR2E打印参数设置方法】
在关机状态下，同时按住STATION1和STATION2键开机，等待打印机完成初始化，放入一张A4纸，会打印出操作说明。
按下LOCAL键，机器进入设置状态，会打印出菜单项。
STATION1键是确认，STATION2键是切换，LOCAL键是保存配置。
在“配置模式”中，【接口】- 选择【并口】；【并口仿真】-选择【南天-OKI】
在“OKI配置”中使用默认配置即可。
【驱动安装说明】
本站提供了OKI仿真和EPSON LQ1600K仿真的驱动下载。
【OKI 5530SC驱动安装方法】
1. 下载驱动。点击“OKI仿真驱动【WINXP/WIN7/WIN10驱动 32/64位】”下载。
2. 运行驱动。提示是否安装“Drvsky.com 打印机”，点安装，完成安装会自动添加“Oki 5530SC”打印机。
3. 设置端口。打开控制面板-设备和打印机，找到Oki 5530SC打印机，右键选择“打印机属性”，查看“端口”选项，默认是选择LPT1端口，如果是USB转接线使用USB001之类的端口。
This is confusing and as you are a beginner, I'm thinking you may not understand all the licensing requirements or the technical requirements. It's important to realize that these are different things.
1) You need to know how to get things setup and running (technical)
2) You need to license everything properly (legal / licensing)
For the licensing part of it:
You need a Server CAL for every user / device that will access the Server. You mentioned 50 users above - is that how many you have? If so, you need 50 User CALs.
For RDS / Terminal Server access you need an RDS CAL for every user that will access for the Server for non admin work. You said you have 3 users that will be doing this? You need 3 RDS CALs.
Does that make sense?

First off, use Wireless Channel 1, 6, or 11. Using channel 9 can cause "overlap" with neighboring wireless networks around you, which is bad. Using channel 1, 6, or 11, allows for co-channel existence and "airtime fairness". In other words, nearby wireless networks will all cooperate and transmit at better speeds. More info here: Why Channels 1, 6, and 11.
2. You should also try Wireless Mode: N-Only. Using B/G/N-Mixed can slow down wireless N devices because you may have to dedicate some time to B/G airwaves.
3. Lastly, for your Wireless Band Selection, try just using 20 MHz. Using 40 MHz with a 2.4 GHz radio is not recommended in dense residential areas.

Each individual port can be configured as Passive LACP, Active LACP or a Static LAG port.
| Property | Description |
|---|---|
| Mode (default: passive) | Specify LACP packet exchange mode or Static LAG mode on ports:
|
| Property | Description |
|---|---|
| Group | Specify a Static LAG group |
| Trunk (read only) | Represents group number port belongs to. |
| Partner (read only) | Represents partner mac-address. |

Hello, why are you configuring LAG ports as static? and the second one, to configure a LAG with SwOS it's like a LACP so it has some modes where those switches can negotiate the LAG port:
Passive: Place port in listening state, use LACP only when it's countrary port uses active LACP mode
Active: Prefer to start LACP regardless countrary port mode
Static: Place port in LACP mode=on
So if you want to configure a LACP link you need to get this combinations on both sides:
Active - Active
Active - Passive
On - On
https://forum.mikrotik.com/viewtopic.php?t=138066
You can do and should do lacp
This is exactly what you need, 2 links combined for reliability and redundance.
Rstp has nothing to do with this.
Lacp well there is not much to configure, it is missing long and short timeouts but thats it, there is very little configuration. Just make sure that one of sides is in active mode, or set both to active.
Static team or static lag is same as lacp, but you have to define ports, specific ports on which team is made.
For me, lacp and static teaming are not working at all on my server 2016 box with 3 nics...
Whenever you attempt to visit a website with an invalid security certificate, you may get a warning that says:
This option will only work for requests to localhost over HTTP.

Note: Only perform these steps if you’re sure of what you’re doing and are sure that there is no attempt to compromise your connection.

An IP address IP1 is more private than IP2 if 1) IP1 is localhost and IP2 is not, or 2) IP1 is private and IP2 is public.
