Is this quality range right?

lbschenkel commented 1 year ago

I'm using driverless to generate a PPD for my Brother MFC-L2730DW laser printer (debug output included at the bottom).

The printer publishes the following attributes:

        document-format-supported (1setOf mimeMediaType) = application/octet-stream,image/urf,image/pwg-raster
        printer-device-id (textWithoutLanguage) = MFG:Brother;CMD:PJL,PCL,PCLXL,URF;MDL:MFC-L2730DW series;CLS:PRINTER;CID:Brother Laser Type1;URF:W8,CP1,IS4-1,MT1-3-4-5-8,OB10,PQ3-4-5,RS300-600-1200,V1.4,DM1;
        urf-supported (1setOf keyword) = W8,CP1,IS4-1,MT1-3-4-5-8,OB10,PQ3-4-5,RS300-600-1200,V1.4,DM1
        document-format-preferred (mimeMediaType) = image/urf
        print-quality-default (enum) = normal
        print-quality-supported (1setOf enum) = normal,high,draft
        printer-resolution-default (resolution) = 600dpi
        printer-resolution-supported (1setOf resolution) = 600dpi,300dpi,1200dpi
        pwg-raster-document-resolution-supported (resolution) = 600dpi

Given the above I was expecting the 3 quality profiles to be 300/600/1200 with a default of 600. But the PPD generated by driverless contains:

*DefaultResolution: 1200dpi
*cupsPrintQuality Draft/Draft: "<</HWResolution[300 300]>>setpagedevice"
*cupsPrintQuality Normal/Normal: "<</HWResolution[1200 1200]>>setpagedevice"
*cupsPrintQuality High/High: "<</HWResolution[1200 1200]>>setpagedevice"

I have read the code and my understanding of the implementation is that:

it tries to build a sorted table of supported resolutions
it sees that the printer supports URF and ignores all other formats (and their resolutions)
it only picks the lowest (300) and highest (1200) URF resolutions to add to the list of supported resolutions
then it checks the default resolution for the printer (600) and sees that it's not a in the list of supported resolutions, so it ignores it
it recomputes a default resolution picking the middle entry but as the list has 2 entries, the 2nd entry (index 1 = 1200) is chosen

Is this the intended behaviour in such a scenario? I would argue that, given the attributes above, anything which is not 300/600/1200 can be surprising behaviour to the user. It basically collapses the 3 quality profiles into 2.

In particular, would it be possible to elaborate as to why the algorithm determining the resolution choices for URF only picks the worst/best resolutions and ignores everything in between?

Hey there @lbschenkel !!

You can try using the following command to print specifically in 600 dpi:

lp -o media= <Page Size> -o resolution=600dpi FILENAME

Here <Page Size> can be replaced with A4 or any page dimension as needed.

Also I think the algorithm behaviour is expected. A resolution entry can only be nullified if either the resolution list entry is missing or if it contains broken entries.

In your case it might be the second case due to which the following command gets executed: goto bad_ppd;

The function bad_ppd is as follows:

bad_ppd:

  if (common_res) cupsArrayDelete(common_res);
  if (common_def) free(common_def);
  if (min_res) free(min_res);
  if (max_res) free(max_res);
  ...
  return (NULL);

Here the 600 dpi quality gets referenced as bad ppd due to which the current is deleted and next is taken as default.

Further code can be referred to in the following directory : Cups/PPD

Hope this helps :+1: !

tillkamppeter commented 1 year ago

@CodingWarrior33 you cannot force a job to get printed in a resolution not listed in the PPD file. Specifying such a resolution on the command line does not change anything, the option will get ignored and the printer will print with 300 dpi or 1200 dpi.

We have a bug in the code of the PPD generator (file ppd/ppd-generator.c in the source code of cups-filters). You need to find out what is wrong in the code.

CodingWarrior33 commented 1 year ago

@tillkamppeter with the implementation of commit 808f439f73b947eb1b376e2c3d5c576e445de543 does this issue still remain relevant as the file being referenced has been moved to libppd and the repository has been labelled as legacy ?

tillkamppeter commented 1 year ago

Yes, it is still relevant, as even libppd being legacy, we still fix bugs in it.

I have moved it to libppd now.

lbschenkel commented 1 year ago

We have a bug in the code of the PPD generator (file ppd/ppd-generator.c in the source code of cups-filters). You need to find out what is wrong in the code.

Sorry, I'm confused about "what's wrong in the code": the algorithm starting at https://github.com/OpenPrinting/libppd/blob/master/ppd/ppd-generator.c#L612 seems to be clear — if Apple raster is supported, it only takes the lowest and highest resolutions, and ignores anything in between. I'm not quite sure what is the reasoning behind this and why it is only done for Apple raster.

Given that you said "we have a bug in the code" I'm assuming that you agree that the generated PPD, given the published printer attributes, is sub-optimal. It makes no sense to me to have 3 quality profiles and only use 2 resolutions from the printer attributes (worse: ignoring the printer's "best" resolution in terms of tradeoff toner/quality/speed).

In my naïve thinking I would assume that the PPD's draft/normal/high quality profiles should map to the printer's lowest/default/highest resolutions in most circumstances.

tillkamppeter commented 1 year ago

@lbschenkel the reasoning behind only taking the lowest and the highest resolution from the resolutions in urf-supported is that perhaps neither @michaelrsweet nor me ever have seen an urf-supported entry with three resolutions. The original code of the PPD generator comes from @michaelrsweet and I have overtaken it, assuming that he knows urf-supported, with so many years working at Apple ... So now the bug is spotted, the PPD generator only supports urf-supported with two resolutions. This piece of code needs to get fixed, to support any number of resolutions, ideally taking the highest resolution for high quality, the lowest resolution for draft quality and the "middle" one for normal quality. If the number of resolutions is odd, it is clear, if it is even, we should "round down", for example taking the first entry of two available ones. @CodingWarrior33 could you do this fix?

lbschenkel commented 1 year ago

@tillkamppeter: it makes some historical sense, yes.

I actually see 2 issues:

the one we are discussing here (resolutions being dropped)
in case there are only 2 usable resolutions (or 1), the PPD should only contain draft/high or normal/high quality profiles instead of draft/normal/high, because as an user it is confusing when multiple quality profiles are made available but some of those are actually identical to other worse/better profiles

lbschenkel commented 1 year ago

ideally taking the highest resolution for high quality, the lowest resolution for draft quality and the "middle" one for normal quality.

This is sensible and would be my choice as well, but perhaps even better is picking printer-resolution-default for the normal quality profile, assuming it is among the available resolutions and it is > lowest and < highest (in order to avoid "duplication" of quality profiles).

CodingWarrior33 commented 1 year ago

@tillkamppeter @lbschenkel what I understand is that I need to implement a resolution array. 1.The resolution array if having odd length can take resolutions as mentioned by taking highest, middle and lowest. 2.For even length the array will have to choose between 2 profiles (preferably the lower one) as there is no perfect "middle" for an even entry. 3.If lesser usable resolutions are available then we should consider revising the profiles to only draft/default(normal) as there are lesser supported resolutions to avoid duplication. 4.The printer-default resolution should be always preferred over others.

lbschenkel commented 1 year ago

@tillkamppeter : Agree with all the points, this is what I was suggesting as well (perhaps poorly phrased).

lbschenkel commented 1 year ago

Trying to phrase it better:

Regarding point 4, if the algorithm is if(default > lowest && default < highest && default in [resolutions]) then normal = default then you're also potentially addressing points 1 and 2. Points 1 and 2 then became the fallback algorithm in case the aforementioned test is false.

This fallback algorithm could also be picking the highest resolution that is <= (lowest + highest)/2. That is closest to the middle of the road, so to speak, and then also becomes indifferent to even/odd number of elements or an uneven distribution of resolutions in the list.

tillkamppeter commented 1 year ago

Yes, so we will do:

Draft Quality: Lowest resolution
High Quality: Highest resolution
Normal Quality: If there is printer-default-resolution and this resolution is in the list, use it. If not, use the "middle" one, rounding down if the number of available resolutions is even.
Duplicate resolutions are no problem, at least if there are other things which also get changed by the print quality.

CodingWarrior33 commented 1 year ago

Draft Quality: Lowest resolution

Duplicate resolutions are no problem, at least if there are other things which also get changed by the print quality.

@tillkamppeter @lbschenkel this sums it up and to add to above mentioned we still keep duplicate resolutions unless there is an effect on print quality due to other factors.

lbschenkel commented 1 year ago

Understood, although if you look at the PPD I posted in my printer the quality is only affecting resolution, and nothing else.

CodingWarrior33 commented 1 year ago

Ok, will work on the above stated points.

lbschenkel commented 1 year ago

Sorry to hijack this for an off-topic question, but: does it still make sense to have two separate PPD generators: "ippeve.ppd" and "drvless.ppd"? I understand why that was necessary when CUPS was under Apple stewardship, but now that CUPS became an OpenPrinting project, shouldn't both be unified?

tillkamppeter commented 1 year ago

The reason why cups-filters had and now libppd has its own PPD generator is the fact that it is used by cups-browsed to generate PPDs for a cluster of different printers. This needed adaptations in the PPD generator and therefore I was not able to re-merge the CUPS one and the libppd one. Now the PPD generators will fade away with the demise of PPD file use in the general printing workflow and therefore the effort of trying to re-merge them is not worth it any more. cups-browsed will later on be turned into a Printer Application for clustering and adapting to old enterprise distros (with CUPS <= 1.5.x) and so it will not need the PPD generator any more. CUPS will not contain its own PPD generator any more starting with version 3.0. So there stays a single PPD generator in libppd and probably I can deprecate this one right away (to go away in libppd3) as the legacy task of libppd is reading and understanding/converting to IPP attributes PPD files, not creating them.

tillkamppeter commented 1 year ago

Fixed by Pull Request #3 from @Kappuccino111. Thanks a lot.

lbschenkel commented 1 year ago

What version of CUPS will this be included in, so I can test?

tillkamppeter commented 1 year ago

@lbschenkel The fix is not done in CUPS but in libppd, a part of cups-filters. If you are using a Linux distribution with cups-filters 1.x I could backport the fix to cups-filters.

lbschenkel commented 1 year ago

I use Debian and Arch, so I would appreciate if you could backport this to cups-filters.

tillkamppeter commented 1 year ago

@lbschenkel There is a backport of this fix into cups-filters 1.x now:

https://github.com/OpenPrinting/cups-filters/pull/515

Could you try it out?

OpenPrinting / libppd

Is this quality range right? #2
