| deekej | hey guys :) is there any official date on ghostscript-9.20 release yet? :) | 11:27.48 |
| Robin_Watts | deekej: No official date. | 11:31.04 |
| deekej | okay, thanks :) | 11:31.18 |
| Robin_Watts | But we would hope to get it out by the end of september normally. | 11:31.18 |
| deekej | that seems like a good timing for me :) | 11:31.36 |
| Robin_Watts | This year, one of our staff members has left, which means testing might take a bit longer, but we're still trying to hold to the 'release in september' plan. | 11:31.56 |
| deekej | np :) | 11:32.19 |
| KlausedSource | hey everyone, i have a canon printer (A1). I printed a file and used the method "print to file" in the driver (on windows). the file is called *.prn. I tried using the pcl6 component from GhostPDL to convert this to pdf (for tests). it didn't work. the file itself (the prn one) is thousands of lines full of binary gibberish. all i can read is the first few lines: https://bpaste.net/show/9a1f03da3256 | 14:49.01 |
| | in the end i want to use the WxH and number of pages to use them for accounting. Is there any way i can get this information from a file like this? | 14:49.38 |
| kens | Well, PCL *is* binary gibberish, what else were you expecting ? | 14:49.55 |
| | WHen you say 'it didn't work' what exactly do you mean ? Gave an error, produced something you think is incorrect, something else ? | 14:50.29 |
| | What version of GhostPDL are you using, and where did you get it ? ON what OS ? | 14:50.49 |
| | Rahter than post a screenshot. Put the file (a nice simple one) on a public URL somewhere (DropBox works) and post the URL here, then we cna look at it | 14:51.38 |
| KlausedSource | kens, i use ghostscript 9.15 on gentoo linux (installed via the distros package manager). and downloaded ghostpdl 9.15 from ghostscript.com | 14:53.16 |
| kens | Well, that's a 2 year old version of GhostPDL then, you should try 9.19 which is the current release (soon to be superseded by 9.20) | 14:53.56 |
| Robin_Watts | KlausedSource: In theory, you can run the pcl file through gpcl6 using -sDEVICE=bbox and it'll give you the answers you need. | 14:54.43 |
| KlausedSource | kens, https://serilda.servebeer.com/owncloud/index.php/s/3Bgjs6XaF2dpu1m | 14:55.01 |
| | password is prn | 14:55.07 |
| kens | Looks to me like it has a bunch of crap on the front of the file. Possibly something canon-specific | 14:56.08 |
| kens | goes delving | 14:56.26 |
| KlausedSource | kens, i tried converting it to pdf with -sDevice=pdfwrite and -sOutputFile=blabla.pdf | 14:56.58 |
| kens | going to need a minute to rebuild Ghostpdl | 14:57.02 |
| Robin_Watts | Ignore everything up to the first @PJL ? | 14:57.03 |
| kens | No its not that simeple I think | 14:57.10 |
| | Give me a second till this builds | 14:57.17 |
| KlausedSource | when i did this it kept prompting "finished page {1,2,3,4,5,6, and so on} press enter to continue" although the document only had 10 pages | 14:58.03 |
| kens | PCL is a funny language | 14:58.19 |
| | If it doesn't think you are sending PCL data, then it treats it as text | 14:58.30 |
| | And prints that. So if you send (for example) a PDF file to it by mistake, it will print the contents of the file | 14:58.53 |
| | THis often leads to lengthy printouts of complete nonsense | 14:59.04 |
| chrisl | Whatever is in that file, I don't think it is compatible with the HP PCL printer(s) we emulate | 14:59.09 |
| kens | Its certainly very strange looking | 14:59.33 |
| | It uses PJL, but not (apparently) PCL | 14:59.41 |
| | I'm forced to guess this is a Canon-specific language | 14:59.55 |
| chrisl | The PJL doesn't specify a PDL to switch to, which I think it ought to | 15:00.10 |
| kens | I don't think it has to if the following is PCL | 15:00.22 |
| | Because HP pritners assume that he default language is PCL. | 15:00.38 |
| HenryStiles | Had a quck look ... I'd guess a proprieary pcl dialect | 15:00.52 |
| kens | Though it is, obviously, still good practice to do so | 15:00.53 |
| | HenryStiles : yeah that's what we are thinking | 15:01.02 |
| Robin_Watts | KalusedSource: Really? Canon not HP ? | 15:01.56 |
| kens | KlausedSource : There's no way we can deal with this, its not PCL. | 15:02.12 |
| KlausedSource | Robin_Watts, yes it is a canon | 15:02.16 |
| Robin_Watts | Which canon? | 15:02.26 |
| kens | But the driver is using what 'looks like' a Canon-specific language, not PCL | 15:02.34 |
| | So we can't interpret it | 15:02.40 |
| | You'll need to use a different printer, or a different emulation of htat printer | 15:02.54 |
| KlausedSource | Robin_Watts, imageprograf ipf605. | 15:03.17 |
| | - the . | 15:03.22 |
| Robin_Watts | Those support GARO or HP-GL2 apparently. | 15:03.31 |
| | We don't support GARO. | 15:03.47 |
| kens | Indeed | 15:03.52 |
| | And neither of them is PCL | 15:03.57 |
| KlausedSource | so there is no way to achieve what i am looking for with this printer? | 15:04.19 |
| Robin_Watts | We *might* support some HP-GL/2 stuff as part of PCL, but I'd not want to rely on it. HenryStiles would know more. | 15:04.26 |
| kens | The spec sheet I see here says Language : GARTO (Canon proprietary) | 15:04.28 |
| Robin_Watts | KlausedSource: Not using an unmodified gs, no. | 15:04.41 |
| | (or gpcl6) | 15:04.51 |
| kens | We do support HP-GL/2, but its not PCL. And there's no way we can support an unpublished proprietary language from Canon | 15:05.02 |
| KlausedSource | so unless I hack into canon and download their proprietary spec and implement this in gs i can't use it right? | 15:05.23 |
| kens | If you think you can do that, then go ahead :-) | 15:05.37 |
| KlausedSource | kk np thx for your help guys | 15:05.48 |
| kens | Ghostscrtip and GhostPCL can't support languages other than PostScript, PDF, PCL, PXL, XPS | 15:06.01 |
| HenryStiles | KlausedSource: for what it's worth I would bet the embedded raster in that file is jbig. | 15:07.07 |
| kens | Apparently GARO = Graphics Arts language with Raster Operations | 15:07.41 |
| HenryStiles | maybe not with a color priniter, not sure | 15:07.58 |
| kens | HenryStiles : *some* of it is 'PCL-like' | 15:09.57 |
| HenryStiles | kens: yeah I've seen a lot of files where the basic PCL raster commands are used to support a proprietary or non supported raster format. | 15:11.38 |
| kens | Well, the 0xCd 0xCA construct looks like its introducing some non-PCL commands. BU who knows fo saure ?...... | 15:12.18 |
| | Forward 1 day (to 2016/09/13)>>> | |
