| Gehlot | Hi Devs, I am getting a weird issue. Ghostscript is not able to print document in color for some printers. | 09:16.40 |
| | I have tried already tried these flags but no sucess "-sOutputICCProfile=default_cmyk.icc", BitsPerPixel=4/24/8 | 09:18.11 |
| artifexirc-bot | <KenSharp> Gehlot you are going to have to be more specific | 09:19.16 |
| | <KenSharp> What do you mean by 'print' ? | 09:19.22 |
| | <KenSharp> Changing the ICC profile is unlikely to do anything useful | 09:19.38 |
| | <KenSharp> WHat is the complete command line you are using, on what operating system and which version of Ghostscript ? | 09:19.53 |
| Gehlot | OS: Windows 10 | 09:23.11 |
| | "-empty", | 09:23.55 |
| | /OutputFile (%printer% HP LaserJet M) /UserSettings <</DocumentName (ColorPrintTestDoc)>> (mswinpr2) finddevice putdeviceprops setdevice ", | 09:23.58 |
| artifexirc-bot | <KenSharp> That doesn't look like a Ghostscritp command line | 09:24.31 |
| | <KenSharp> The PostScript is fine but what's hte '-empty' ? | 09:24.50 |
| Gehlot | I have C# wrapper that takes parameters in form form of array of string | 09:26.14 |
| | Ghostscript version is 8.71 | 09:27.21 |
| artifexirc-bot | <KenSharp> OK so firstly are you aware of the licence ? If you 'wrap' Ghostscript inside a C# wrapper then you aren't (almost certainly) conforming to the AGPL. That doesn't mean its a problem, it depends what you are doing. Personal projects are almost certainly OK | 09:27.23 |
| | <KenSharp> The next thing is that I (obviously) can't give you any pointers when you use that, I can only offer any guidance based on actual Ghostscript | 09:27.53 |
| | <KenSharp> So I'd suggest that you try the same thing you are doing but using the Ghostscript command line. Otherwise its going to be very hard to make any concrete suggestions | 09:28.22 |
| chrisl | Oh, wow, using a 10+ year old gs version? Probably try something newer!! | 09:28.38 |
| artifexirc-bot | <KenSharp> Oh I missed the version | 09:28.51 |
| Gehlot | I am working on a proof of concept project so | 09:28.53 |
| artifexirc-bot | <KenSharp> Yeah the amazing thing is that it actually works at all 🙂 | 09:29.02 |
| Gehlot | OK I will test with latest version | 09:29.29 |
| artifexirc-bot | <KenSharp> Please try it out using the command line | 09:29.42 |
| | <KenSharp> If that has a problem then we can offer guidance | 09:29.58 |
| Gehlot | ok | 09:31.04 |
| chrisl | FWIW, I would also be very wary about using finddevice or putdeviceprops, because they're not really Postscript..... | 09:38.31 |
| artifexirc-bot | <KenSharp> They are (sadly) documented in our own documentation for the mswinpr2 device though I'm afraid 😦 | 09:39.05 |
| | <KenSharp> At least, I think they are.... | 09:39.19 |
| chrisl | I'd still be wary about it, especially as there shouldn't be any need for them | 09:39.34 |
| artifexirc-bot | <KenSharp> And by documented, I really mean used in an example | 09:39.38 |
| chrisl | Because it's trying to support running in Level 1 mode, which we no longer support :-( | 09:40.49 |
| artifexirc-bot | <KenSharp> We should probably update the documentation to use setpagedevice (or simply command line parameters) | 09:41.15 |
| chrisl | I actually thought we had - shows what I know! | 09:41.44 |
| artifexirc-bot | <KenSharp> There's so much documentation for Ghostscript, its hard to remember what there is | 09:42.25 |
| Gehlot | I have tested to print with Latest GS 9.53 for color print issue. Still its coming out black and white | 10:14.50 |
| artifexirc-bot | <KenSharp> OK so what is your command line now ? | 10:15.18 |
| Gehlot | It has command as before | 10:20.14 |
| | -empty, -dPrinted, -dBATCH,-dNOPAUSE, -dNOSAFER, -dNoCancel, -dPDFFitPage, -sOutputICCProfile=default_cmyk.icc -c mark /NoCancel true /QueryUser 3 /OutputFile (%printer% HP LaserJet M) /UserSettings <</DocumentName (ColorPrintTestDoc)>> (mswinpr2) finddevice putdeviceprops setdevice -dNORANGEPAGESIZE", | 10:20.15 |
| artifexirc-bot | <KenSharp> Well you **really** shouldn't use -dNOSAFER but let's ignore that for now | 10:20.41 |
| | <KenSharp> So does your pritner name really begin with a space ? | 10:20.59 |
| | <KenSharp> You've got the name as "%printer% HP LaserJet M" | 10:21.21 |
| | <KenSharp> with a space between % and H | 10:21.30 |
| Gehlot | No | 10:21.58 |
| | Its typo | 10:22.01 |
| artifexirc-bot | <KenSharp> Then start by removing the space | 10:22.06 |
| | <KenSharp> OK so when you execute that, do you get a print dioalog ? | 10:22.24 |
| | <KenSharp> Actually there are more problems there | 10:22.49 |
| | <KenSharp> You've -dNoCancel as well as setting NoCancel in the PostScript fragment. Use one or the other, not both | 10:23.14 |
| Gehlot | ok | 10:23.29 |
| artifexirc-bot | <KenSharp> The PostScript following -c includes -dNORANGEPAGESIZE so I'd expect that to throw a PostScript error | 10:23.52 |
| | <KenSharp> Because that's not valid PostScript. | 10:24.01 |
| | <KenSharp> And in any event you shouldn't use it, it has no effect on the mswinpr2 device | 10:24.25 |
| Gehlot | But I am confuse How It can affect some printers. Some printer print in color some not | 10:24.26 |
| artifexirc-bot | <KenSharp> You can also drop the OutputICCProfile, that won't be doing anything | 10:24.42 |
| Gehlot | Yes I tried it | 10:24.53 |
| artifexirc-bot | <KenSharp> Again, do you get a print dialog when you execute this ? | 10:25.06 |
| Gehlot | No | 10:25.14 |
| artifexirc-bot | <KenSharp> Well then I imagine that's your problem | 10:25.23 |
| | <KenSharp> The mswinpr2 device is not intended as a print server, its intended to be used by a single user who wants to print stuff | 10:25.51 |
| | <KenSharp> I expect the default state of your pritner is 'gray' | 10:26.09 |
| | <KenSharp> If you want the pritner to print in colour you need to change its default to 'colour' | 10:26.22 |
| Gehlot | Yes My intension is same that use will print pdf from my application without any interaction | 10:26.37 |
| | We have already configured it as print in color | 10:26.57 |
| artifexirc-bot | <KenSharp> Well as I said, what you will get is whatever the default setting of the pritner is | 10:27.06 |
| | <KenSharp> ThYou have to have the **default** setting of the pritner be in colour as I recall | 10:27.31 |
| | <KenSharp> The mswinpr2 device doesn't change it | 10:27.40 |
| | <KenSharp> If you don't set the printer name then you should get a print dialog. I'd suggest you try that, and look at the settings for the printer, I expect they will show up as grayscale if you try that | 10:28.57 |
| Gehlot | At printer configuration we have set it to print in color by default also When We I use gs to print its fails | 10:28.58 |
| | I am setting printerName in command line | 10:29.18 |
| artifexirc-bot | <KenSharp> When you say 'fails' what do you mean ? AN error ? | 10:29.18 |
| Gehlot | sorry I mean B/W print | 10:29.32 |
| artifexirc-bot | <KenSharp> Yes, and I just said 'don't set the printer name in the command line' | 10:29.55 |
| | <KenSharp> That will (or should) get you a print dialog | 10:30.03 |
| | <KenSharp> Then you can look at teh printer settings that mswinpr2 is using. They will be the 'defaults' for that printer | 10:30.21 |
| Gehlot | am afraid that its main feature of my application that redirect print to pritner without showing any printer selection popup | 10:31.13 |
| artifexirc-bot | <KenSharp> This is what's called debugging | 10:31.26 |
| | <KenSharp> I'm asking you to try stuff and see what it says | 10:31.38 |
| Gehlot | At least for testing I am removie it from command line and test it | 10:31.53 |
| | ok | 10:31.57 |
| artifexirc-bot | <Robin_Watts> Hi @rodrigo.emobix. | 17:59.17 |
| | <Robin_Watts> Gimme a mo, and i'll get you into the other channels. | 17:59.28 |
| | <rodrigo.emobix> Hi! thanks | 17:59.59 |
| | <Robin_Watts> OK, you should be able to see the company channels now. | 18:03.15 |
| | <rodrigo.emobix> yep, I'm seeing them now | 18:05.01 |
