>                 Key: GUACAMOLE-1129
>                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-1129
>             Project: Guacamole
>          Issue Type: Wish
>          Components: RDP
>         Environment: CentOS 7, Debian10, Docker 
>            Reporter: Heiko Beisswenger
>            Priority: Minor
>
> I hope that this is the right place to ask for help on this issue.
> I have tested this on guacamole version 1.2 installed natively on a CentOS 7.8 , on a CentOS 7.7 native installation with guacamole version 0.9.14 and on a docker setup on Debian Buster OS.
> The results were on all setups identical.
> I try to print from a windows 10 client connected via rdp session (pdf download).
> Printing small documents like text only work without problems. 
> I get the pdf download as expected after a short period of time.
> As soon as I try to print larger files with images in it, the resulting pdfs get very big or can't even be downloaded.
> One document I've run tests on is a 628 pages pdf document with pictures and diagrams in it, which original size is 17MB.
> I've printed the first 50 pages wich took about 10 minutes and the resulting pdf was 26MB big.
> Printing the first 20 pages, results in a 10 MB pdf file takes about 4 minutes.
> If I try to "print" more than 50 pages ghostscript works on 100% CPU but won't finish in a reasonable time period.
> Then I took other documents, which one of our customers wanted to print. These are scanned documents with only 4-6 pages, only images. original size 2-4 MB. 
> The Windows 10 printqueue says that the resulting document will be 96MB big. But due to timeout issues it's not available to download at all.
> I did little research and Microsoft says to change the printer settings to "Print directly to the printer".
> https://support.microsoft.com/en-us/help/919543/the-size-of-the-emf-spool-file-may-become-very-large-when-you-print-a
> But It is not possible to change this setting in the guacamole-printer settings.
> I've also tested against another Windows 10 system, same problem here.
> The same tests were run on a Windows 7 system and this dos not show this behavior.
> So this is a Windows 10 guacamole-printer issue.
> Is there any configuration without altering the code that can be changed to make things work again ?
> Thanks
> Heiko
