Mike Jumper commented on GUACAMOLE-1522: ---------------------------------------- When you were connected to the remote desktop using Guacamole, what application was used inside the Windows session to print the PDF file? > Printing is slow for some PDF document > -------------------------------------- > > Key: GUACAMOLE-1522 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-1522 > Project: Guacamole > Issue Type: Bug > Components: guacamole, guacd > Affects Versions: 1.4.0 > Environment: ubuntu 18.04, GhostScript 9.26 (2018-11-20), Windows > Server 2019 > Reporter: Jimmy > Priority: Major > Attachments: Print-Sample.pdf, print-001.ps, print-002-1.ps, > print-003-1.ps > > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
