Jimmy updated GUACAMOLE-1522:
-----------------------------
Description:
I attached a PDF document. (Print-Sample.pdf)
This document has 5 pages.
When printing the PDF file on the Apache guacamole, it took more than 30
seconds until the downloading is started.
Once the downloading is started, it's completed in a short time.
As a result of my analysis, the call of *read()* function takes a long time in
the
*guac_rdp_print_job_output_thread()* function. (src/protocols/rdp/print-job.c)
I captured the print data in the *guac_rdp_print_job_write()* function and
saved them to the files.
I attached some of the print data. (print-001.ps, print-002.ps, print-003.ps)
When I directly use Ghostscript in the terminal to convert them to PDF
documents, Ghostscript works quickly.
{code:java}
$ gs -q -dNOPAUSE -dBATCH -dSAFER -dPARANOIDSAFER -sDEVICE=pdfwrite
-sOutputFile=print-001.pdf -c .setpdfwrite -f print-001.ps
$ cat print-001.ps print-002.ps > print-002-full.ps
$ gs -q -dNOPAUSE -dBATCH -dSAFER -dPARANOIDSAFER -sDEVICE=pdfwrite
-sOutputFile=print-002.pdf -c .setpdfwrite -f print-002-full.ps
$ cat print-002-full.ps print-003.ps > print-003-full.ps
$ gs -q -dNOPAUSE -dBATCH -dSAFER -dPARANOIDSAFER -sDEVICE=pdfwrite
-sOutputFile=print-003.pdf -c .setpdfwrite -f print-003-full.ps{code}
I hope the Apache Guacamole developer team solves this issue.
Thanks.
