Created attachment 15946 [details] Research file of ghostscript command test in 9.25. PDF file data fail to rendering to raster data. We were reported a bug from our printer users: I print file use papersize A5 (Ubuntu 16.04.1(x64),Ghostscript 9.18) is Okay. But, after I update (apt-get upgrade) to Ubuntu 16.04.5(x64),Ghostscript 9.25, I print the same file with the same driver there is an error reports: "Filter Error" I figure out that all the papersize with define "LeadingEdge" can't print success after update. (with "LeadingEdge":A5, Statement, A4(without "LeadingEdge") is print Okay). I view the "CUPS Error Log",there is an error reports when print job fails: "Ghostscript command line: /usr/bin/gs -dQUIET -dPARANOIDSAFER -dNOPAUSE -dBATCH -dNOINTERPOLATE -sDEVICE=cups -sstdout=%stderr -sOutputFile=%stdout -sMediaType=Plain -sOutputType=Pass=1,Direction=1 -r600x600 -dLeadingEdge=1 -dMediaPosition=7 -dDEVICEWIDTHPOINTS=420 -dDEVICEHEIGHTPOINTS=595 -dcupsBitsPerColor=8 -dcupsColorOrder=0 -dcupsColorSpace=1 -scupsPageSizeName=A5 -I/usr/share/cups/fonts -c \'<</.HWMargins[14.400000 14.400000 14.399994 14.400024] /Margins[0 0]>>setpagedevice\' -f -_ Unrecoverable error: undefined in .putdeviceprops" I think that this is a bug of ghostscript 9.25. Below information are the research of I do: (I am using Ubuntu 16.04.5(x64),Ghostscript 9.25) I am running gs command below (with "-dLeadingEdge=1"): gs -dQUIET -dPARANOIDSAFER -dNOPAUSE -dBATCH -dNOINTERPOLATE -sDEVICE=cups -sMediaType=Plain -sOutputType=Pass=1,Direction=1 -r600x600 -dLeadingEdge=1 -dMediaPosition=7 -dDEVICEWIDTHPOINTS=420 -dDEVICEHEIGHTPOINTS=595 -dcupsBitsPerColor=8 -dcupsColorOrder=0 -dcupsColorSpace=1 -scupsPageSizeName=A5 -o ~/Desktop/out_A5.prn ~/Desktop/d00017-001.pdf Reports an error: Unrecoverable error: undefined in .putdeviceprops I am running gs command below (without "-dLeadingEdge=1"): gs -dQUIET -dPARANOIDSAFER -dNOPAUSE -dBATCH -dNOINTERPOLATE -sDEVICE=cups -sMediaType=Plain -sOutputType=Pass=1,Direction=1 -r600x600 -dMediaPosition=7 -dDEVICEWIDTHPOINTS=420 -dDEVICEHEIGHTPOINTS=595 -dcupsBitsPerColor=8 -dcupsColorOrder=0 -dcupsColorSpace=1 -scupsPageSizeName=A5 -o ~/Desktop/out_A5.prn ~/Desktop/d00017-001.pdf Reports no error. Above all, we think this is a bug of ghostscript that ghostscript can't deal with the flag "-dLeadingEdge" on version 9.25 (version 9.18 is Okay.). My questions are： 1. Do you have any plan to fix it? 2. Is there any workaround?
Regression caused by: http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=478a0a862d25
This fixes the problem, and I think behaves correctly: http://git.ghostscript.com/?p=user/chrisl/ghostpdl.git;a=commitdiff;h=3b91a3aaeb3b But I'd like Ray to review the commit before I push it.

Now we knew that this a bug of ghostscript(9.25) and you have a solution for it, will you fit it in the next version(9.26) release? And can you offer the accurate time that you release the version that fix this bug? And is there any workaround for our printer driver customers to do the print job normally by using paper size like A5(with "LeadingEdge")?

No. You simply can't use LeadingEdge with the CUPS device.
I would add: I'm assuming that as the problem arose via the cups print workflow that the "customers" you refer to are users of Ricoh printers that use Linux - i.e. they use Ghostscript as packaged by their distribution. That being the case, in situations like this, package maintainers often pick up patches like this before the feature in an official release of ours. I'd suggest if that doesn't happen for any of you customers, they contact the Ghostscript package maintainer for their distribution, and prompt them to look at this bug, and pull the patch into their package.
Dear Chris, We were reported this error from a lot of users, and almost all of our raster printer drivers were affected by this bug. Since more and more our printer driver users were affected by this bug, can you speed up the process of release the next version (Version 9.26) of ghostscript. And most importantly, our printer driver users can't do their normal print jobs. So, we are eagerly hopping that you can offer us a patch to fix this bug before your official release (Version 9.26). >That being the case, in situations like this, package maintainers often pick up >patches like this before the feature in an official release of ours. >I'd suggest if that doesn't happen for any of you customers, they contact the >Ghostscript package maintainer for their distribution, and prompt them to look at >this bug, and pull the patch into their package. Our printer drivers are only supported on Linux Ubuntu OS, so can you contact the Ubuntu package maintainer to pick up this patch to their distribution? Best Regards.

We're planning a release within the next 6 weeks, and we really can't do it any quicker (that is already ~4 months earlier than our normal schedule). > >That being the case, in situations like this, package maintainers often pick up >patches like this before the feature in an official release of ours. > >I'd suggest if that doesn't happen for any of you customers, they contact the >Ghostscript package maintainer for their distribution, and prompt them to look at >this bug, and pull the patch into their package. > > Our printer drivers are only supported on Linux Ubuntu OS, so can you > contact the Ubuntu package maintainer to pick up this patch to their > distribution? The maintainer in question (AFAIK) is Till, who you may have noted was the original assignee for this bug, and also added himself to the CC list for this bug - so he is aware.

YangGuangJing, please report a bug on https://bugs.launchpad.net/ubuntu/ for the package "ghostscript". Tell also which Ubuntu versions suffer this bug. Thanks.

Dear Till, We had report this bug on ubuntu: https://bugs.launchpad.net/ubuntu/+source/linphone/+bug/1800062 New, we are eagerly hopping that you can offer us a patch of Ubuntu 16.04 to fix this bug(and the accurate time that we can pick up the patch). After that(16.04),we hope that Ubuntu 18.04 patch can also be offered.
Hint: Read the documenation. Look for .htm files that contain "halftone". Ghostscript supports PostScript Level 3 halftones and includes some tools to do special dithering/halftoning.
