The reason for substituting pdftops by another renderer is as follows: Under OS 15.1 I realized that certain documents needed a lot of time to be printed by my Kyocera Ecosys FS-1300D PS printer; this could be much improved by changing the renderer. Typically, this concerned PDF files containig a mixture of vector and bitmap graphics. This problem is known, see /usr/share/doc/packages/cups-filters/README from package cups-filters-1.25.0-3.3.1.x86_64 , section "POSTSCRIPT PRINTING RENDERER AND RESOLUTION SELECTION". This problem persists under OS 15.3 using the default cups setup. As an example I attach a single paged PDF file "test.pdf". Printing this file on my Kyocera FS-1300D PS printer via lpr -o pdftops-renderer=pdftops test.pdf takes about 870 s. Using the cups debug mode reveals that during this printing process pdftops is effectively called via pdftops -level1 -origpagesizes -nocenter -r 1200 -optimizecolorspace test.pdf test.ps (last two file arguments exchanged by myself for testing purposes). This command takes less than 1 s on my linux box. However, test.ps has a size of 270 MB. Hence, the 870 s observed for printing test.pdf are probably due to data transfer to and / or processing by the printer. (The printer is connected via 100 mbit/s ethernet, it has 544 MB of RAM.) In contrast, pdftocairo -level3 -origpagesizes -nocenter -r 1200 -ps test.pdf test.ps yields test.ps with a size of only 146 kB. Since I cannot use pdftocairo with the default cups setup of OS 15.3, I tried the two other renderers mentioned in /usr/share/doc/packages/cups-filters/README: mupdf and gs. Of these, mupdf does not yield any output (I didn't inspect this case), but gs succeeded: For the command lpr -o pdftops-renderer=gs test.pdf printing takes about 70 s. Under OS 15.1 I used pdftocairo also as renderer for a current Kyocera PS printer (ECOSYS P2040dn). However, some printouts showed artifacts. Bottom line: Changing the renderer is not always the optimal solution, but is definitely worth giving a try. -- You are receiving this mail because: You are on the CC list for the bug.
