Title:
cups converts multiple times between pdf and ps
Status in cups package in Ubuntu:
Expired
Bug description:
Binary package hint: cups
I guess this bug could be related to bug #382379 but as I'm not really
shure I didn't append to that pretty overloaded bug.
Printing a PDF can take very long (and I'm not shure if the print jobs
really end successfully). I have tried three cases:
CASE 1:
I have a PDF (a converted PowerPoint presentation, about 125 slides, 10 MB).
The PDF mainly consists of text, formula and vector graphics. There are a few
JPGs in it, too, but they are low resolution only.
As more than 120 pages is very much to print and the font size is big,
too, I wanted to print 2 slides on one DIN A4 page. Okular (or
kprinter?) has a function for this so I tried to use it.
After about 1 hour I didn't have at least one printed page but a CPU
intensive gs process running and a temporary PS file that was far bigger than
200 MB.
After some more waiting I cancelled the printing job.
CASE 2:
I had the suspicion that gs processed each file as seperate image to fit two
of them on one page. So I tried Adobe reader togive out a ps file with 2 slides
on one page hoping that this application is a bit more efficient.
It really is more efficient and the resulting PS file was "just" about
130 MB which I guess is not too bad if the Reader has converted some
vector grafics into rasterized images (for compatibility reasons for
example). I expected it should be no big problem to print out this
"printer ready" PS file... So I opened in Okular and tried to print
it. But after some time the printing wasn't even started and it took a
closer look at the processes running:
$ ps -fA | grep gs

(Cups is process 2481)
So it seems as if the printer ready PS file is converted to PDF and back to
PS again by Cups and that gs is processing it in some way, too.
This semed very inefficeinto me so I canceled the printing job again as it
probably wouldn't be processed any time soon.
CASE 3:
I thought maybe Okular and Cups couldn't communicate that the file was
already ready for printing. So I tried to print the file directly using "lp" -
but the problem was the same. And also printing diectly from Adobe Reader had
this effect (but I guess this is hardly surprising as it seems to use "lpr").
------------------
Maybe the problem is something completely different, but that's all I could
find out. The only thing I know for sure is that I have no proper solution to
print such documents which I need for studying :-(
But I hope that this bug can be solved. I will help as good as I can.
