---------------------------------------
Summary: Handle printing synchronously
Key: GUACAMOLE-49
URL: https://issues.apache.org/jira/browse/GUACAMOLE-49
Project: Guacamole
Issue Type: Sub-task
Components: RDP
Reporter: Michael Jumper
Assignee: Michael Jumper
As mentioned in GUACAMOLE-44:

Download via SFTP or RDPDR is working perfectly with the new changes. Printing,
however, is not. The RDP printing code begins streaming immediately, not
waiting for an "ack" from the client.
This means the GET request to the stream endpoint will likely occur *after*
data has already been sent, resulting in data being dropped. If the GET request
occurs after the stream has closed, then it will block until some other stream
with that index is opened, leading to mismatches in the downloaded results.

The print process within the RDP connection needs to be modified to wait for
the initial "ack", or blobs may end up being dropped.
