# Printing/Scanning Compression
For Windows desktop clients (full and basic), Parallels RAS v15.5 and higher includes **Universal printing compression policy** and **Universal scanning compression policy** options. These options allow system administrator to adjust printing and scanning compression levels via client policy settings in the RAS Console.
To set printing and scanning compression policies:
1. In the RAS Console, select the **Policies** category.
2. Right-click an existing policy and choose **Properties**.
3. In the **Policy Properties** dialog, navigate to **Session** > **Experience** > **Compression**.
4. Select one of the following options from the **Universal printing compression policy** or **Universal scanning compression policy** drop-down lists:
* **Compression disabled**
* **Best speed (uses less CPU)**
* **Best size (uses less network traffic)**
* **Based on connection speed** (default)
If the type of printed or scanned documents is predictable — for instance, your documents are always very small or always very large — you can benefit by selecting an appropriate compression policy. However, compression brings the most benefit to network connections with limited bandwidth or latency when printing or scanning often slows down thus negatively affecting user experience.
Parallels recommends using the **Best size** compression policy to make printing/scanning jobs smaller and transfer them faster if the client devices are powerful enough from the CPU and memory perspective. If the client devices are not powerful enough, the **Best speed** option policy should be used.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.parallels.com/landing/ras-best-practices-guide/printer-and-drive-mapping/printing-scanning-compression.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
