Status in “cups” package in Ubuntu: Expired Bug description: > uname -a Linux magrathea 3.2.0-57-generic #87-Ubuntu SMP Tue Nov 12 21:35:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux > cat /etc/os-release NAME="Ubuntu" VERSION="12.04.3 LTS, Precise Pangolin" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu precise (12.04.3 LTS)" VERSION_ID="12.04" > Using cups version 1.5.3 I have a Brother HL-4070CDW, which is a color duplex laser printer. I've attached it with USB. The printer has 320MB of memory, so the problem seems to lie somewhere in the spooling or pre-processing. I am printing directly with lp and lpr. Printing certain files takes far too long. For example, I have a 35MB PDF file, 9 pages of text with some large-ish JPEGs. The printer will print a page, one sided or two sided, and then stop. Constantly refreshing the CUPS page at localhost:631 reveals that only a couple of pages come through at a time. Htop reveals that pdftops -level2 -origpages -r 300 /tmp/somefile is running all the while sending some trickle of data to the printer. Thinking there was some problem here, I ran pdftops on the file itself, and instantly got a 45MB ps file, again, the printer has over 300MB of memory, so the problem doesn't lie there. When I tried to print this ps file with lpr -l (i.e., raw file mode), there was no speedup. Also, IIRC pdftops is still being run when I invoke lpr -l on the ps file, which seems totally wrong. I enabled debug level logging in CUPS and see that the data is being sent 8 kilobytes at a time to the printer. Considering this is USB 2.0, I don't understand why the whole file isn't transferring almost immediately, because, as I reiterated, the printer has more than enough available memory. This print job should spool immediately and allow my printer to run at its maximum output speed, but again, there are gaps between each page or 2 page spurt of up to a few minutes. I have attached the CUPS log in case that may be of use. Please let me know if there are any details I omitted or any information or command outputs you need to diagnose this problem and recommend a solution. Any help you folks can render will be greatly appreciated!
