@cliddell Wow, thank you for all these informations. As I said before, my first sample (gmap.pdf) prints quickly now with pdftocairo. For this document, it seems that few extra processing is done.
However, the second sample (see appout of my printer test page, also created by Cairo) was still slow to print, even with pdftocairo (with much extra processing, as you describe). If I choose (as you suggested) 600 dpi instead ProRes 1200, this sheet is printed in less than a minute. It's not "quick" but acceptable now for my home need. I see some differences on the intensity of the logo and dashed lines, but overall the quality appears to be good enough. So I now set this printer in 600 dpi by default. I continue to observe that pdftocairo is quicker (big difference for gmap.pdf), so I conserve this setting also. Is there any drawback to this? If not, why not set pdftocairo as the default renderer, for postscript printers? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/1476705 Title: postscript printer hideously slow in some cases (pdftops) Status in poppler package in Ubuntu: New Status in system-config-printer package in Ubuntu: New Bug description: With my (old) postscript printer, print a single page can take many minutes on some situations. It happens with some PDF files (not all) and Firefox printing of Google map, for example. When this happens, I observed in system monitor that pdftops is running continuously. After some manual PDF -> PS conversions, I see that pdftops inflates the file size for problematic cases, but is ok for other files (size similar to the original file, or even smaller). I don't know if modern Postscript printers can handle this quickly, but it's unacceptable here and certainly not an efficient way to print those files. So I suspect that pdftops should be fixed. For example, I join a problematic pdf produced by Google Map in Firefox. I tried many conversions. As you can see, I get a much larger file (36 times) with pdftops. It is worse with pdf2ps (and it takes longer to process), so replace pdftops by pdf2ps is not an option for me. However, pdftocairo quickly produces an efficient file. I have the same success if I open the PDF file with Evince and print it as a Postscript file. I get a similar file if I print to PS directly from Google Map (Firefox). Of course these small PS files produced by pdftocairo, Evince of Firefox print flawlessly on my printer. See also Bug # 1095498 which I suspect is the same (old) thing, but I fill a new one since it doesn't seem to be printer specific. Of course, another workaround could be to use a PCL driver but no one is available for my printer (HP Color Laserjet 2605dn).
