You should probably look at a later version than that - 0.9.14 is the latest released version, but 1.0.0 will be out very soon (by tomorrow, I believe). > If I print a PDF (450 kB) to Guacamole Printer, I see in the Printqueue, > that the Printjob is about 5 MBytes big and it takes about 2 Minutes. > If I save the PDF on my Client, the PDF Size is again 450 kB. > > A PDF with 2 MB size have 15 MB in the Printqueue. > > I would fully expect this behavior, and say that it's probably not just Guacamole that behaves this way. PDFs contain built-in compression techniques, which means the size of the PDF at rest is going to be smaller than the size of the actual data in the file. When printing, either to Guacamole's printer or to a physical printer or copier, the data has to be uncompressed and rendered into a certain format based on the type of printer, type of driver, etc. Thus, it is not surprising, nor abnormal, to expect that a file could increase to several times its size in the print spool, depending on what it is in the file. As far as the amount of time it takes, that's more a function of the compute power and RAM available to you - because that data has to be unpacked and rendered, the more RAM and faster CPU you have, the faster that will happen. With Guacamole, network speed may also impact that - the speed between the remote system and guacd, the speed of the network between guacd and Guacamole Client (if they aren't on the same host), and the speed between the client browser and the system running Guacamole Client (Tomcat). -Nick
