| Antonio81 | Hello everyone | 08:42.50 |
| | how are you? | 08:42.54 |
| ghostbot | Antonio81: you know how it is... | 08:42.54 |
| Antonio81 | is there any contrast option when creating the pcl using gs? | 08:43.27 |
| chrisl | Not really. That's not really the purpose of gs. | 08:44.30 |
| | What you *could* do is find a suitable ICC profile and that *should* work. But that is *way* outside what I could help you with | 08:45.47 |
| | And, depending on the input, if you have the knowledge, you could probably define a Postscript transfer function that would create the effect you want. But that's going to be pretty involved. | 08:47.20 |
| Antonio81 | and there is any way to rotate a pdf when creating the pcl? | 08:58.13 |
| | i dont care about the pdf (its landscape) but I want the PCL to have any kind of info and tell the printer that the media is in landscape | 08:59.01 |
| | or else what will happen is that the printer will print half of the media, like it prints a portrait page of a landscape page but without adjusting | 09:00.01 |
| chrisl | There is a (relatively) easy way, and a rather more involved way. If you know the target page size, you should be able to use the "easy" way. | 09:01.31 |
| Antonio81 | the target page size is A4 | 09:03.10 |
| | thanks a lot for your help and patience chrisl | 09:03.52 |
| chrisl | So, if you did something like adding "-dDEVICEWIDTHPOINTS=595 -dDEVICEHEIGHTPOINTS=842 -dFIXEDMEDIA -dFitPage" to your command line, that would (hopefully) produce a portrait page - it's *slightly* dependant in the input, though | 09:12.00 |
| | Where the dimensions of A4 in points is 595 × 842 (w x h) | 09:12.47 |
| Antonio81 | but the width and height points raise a problem | 09:16.58 |
| | this process is fully automatic, since the reception of the pdf until the printing of the document and if I set the width and height points the print gets stuck on the printer as the printer cannot get the printing paper siz<e | 09:17.58 |
| | but I will try it :) | 09:18.32 |
| chrisl | So, the A4 printer can't select A4 paper?? | 09:18.54 |
| | Which specific Ghostscript device are you using? | 09:20.06 |
| Antonio81 | pdfwrite to create the pdf | 09:20.38 |
| | and then ljet4 for the pcl | 09:20.42 |
| chrisl | So, first question is: why the two steps? | 09:21.18 |
| Antonio81 | because the automatic process only prints from the pcl | 09:22.25 |
| | and because there are some pages that we need to adjust or they will get cropped | 09:22.42 |
| chrisl | It seems wasteful to create a PDF, rather than just go straight to PCL | 09:23.25 |
| Antonio81 | ok, thats a good point :D | 09:23.40 |
| | if I can rotate the pcl and make it print the way I want, thats a good point | 09:23.54 |
| | there is something very strange, which is, I am not being able to rotate the pdf using GS but I did it using pdftk | 09:24.33 |
| chrisl | Well, gs and pdftk are totally different tools | 09:24.59 |
| Antonio81 | but if I create a new pdf with gs using the rotated pdf from pdftk the output pdf goes back to landscape | 09:25.13 |
| | I agree, both are very different :) | 09:25.59 |
| | im just trying to find a way to get the result I need for the printing process | 09:26.22 |
| chrisl | I mean totally different tools, with totally different purposes | 09:26.30 |
| Antonio81 | because the process has no human action | 09:26.38 |
| chrisl | pdfwrite has heuristics which try to guess the correct orientation based on the page contents (mostly text orientation), that could be screwing you up | 09:27.15 |
| Antonio81 | yes, is there a way to disable it? | 09:27.37 |
| chrisl | -dAutoRotatePages=/None should disable it | 09:27.41 |
| Antonio81 | it does not work :/ | 09:27.48 |
| | i've been all over stackoverflow and testing | 09:28.03 |
| | I cannot rotate the pdf with gs :( | 09:28.17 |
| | i can send you the file, if you want to take a look | 09:28.26 |
| | brb | 09:28.43 |
| chrisl | You cannot rotate a PDF at all with gs - gs does not manipulate PDf files | 09:28.49 |
| Antonio81 | could you please take a look? | 09:39.35 |
| | https://www.mediafire.com/file/qhexxmzf849dr3z/LX_562T_0162392495_0165479563.pdf/file | 09:39.36 |
| | i would really be thankful | 09:39.49 |
| chrisl | So, that's landscape.... | 09:40.34 |
| | And you want it portrait? | 09:41.58 |
| Antonio81 | yes | 09:43.52 |
| | even if the text becomes vertical | 09:44.00 |
| | there is no problem | 09:44.05 |
| chrisl | This works for me: -dAutoRotatePages=/None -sDEVICE=pdfwrite -o out.pdf -dDEVICEWIDTHPOINTS=595 -dDEVICEHEIGHTPOINTS=842 -dFIXEDMEDIA -dFitPage LX_562T_0162392495_0165479563.pdf | 09:44.53 |
| Antonio81 | let me try :) | 09:51.26 |
| | it didnt work for me | 09:53.28 |
| chrisl | What are you using to view the output? | 09:53.46 |
| Antonio81 | used this command | 09:53.58 |
| | gswin64c.exe -dAutoRotatePages=/None -sDEVICE=pdfwrite -o D:\tmp\LX_562T_0162392495_0165479563.pdf -dDEVICEWIDTHPOINTS=595 -dDEVICEHEIGHTPOINTS=842 -dFIXEDMEDIA -dFitPage D:\tmp\LX_562T_0162392495_0165479563_APR.pdf | 09:53.58 |
| | sorry | 09:54.10 |
| | it did | 09:54.20 |
| | I've changed the input and output | 09:54.32 |
| | thanks a lot | 09:54.34 |
| chrisl | NP | 09:54.40 |
| | FWIW, "-sDEVICE=ljet4 -o out.pcl -sDEFAULTPAPERSIZE=a4 -dFIXEDMEDIA -dFitPage LX_562T_0162392495_0165479563.pdf" goes straight to a portrait PCL file | 09:55.36 |
| Antonio81 | chrisl, I will try everything, thanks a lot | 10:00.24 |
| chrisl | NP | 10:01.24 |
| | Antonio81: One other thing: you might want to experiment with ljetplus (instead of iljet4). It doesn't support compression, so the PCL will be larger, *but* it also doesn't support selecting the page size in the PCL output. Other than those two things, as far as I can tell, the capabilities are the same as ljet4. | 10:22.18 |
| Antonio81 | i have to use ljet4 because the printer auto staples the sheets | 10:33.22 |
| chrisl | Well, the only thing I can see between the two devices that *might* affect that is selecting the paper size, which you said was a problem.... | 10:39.02 |
| Antonio81 | chrisl it worked like a charm | 13:16.06 |
| | thanks a lot | 13:16.09 |
| | got it rotated and stapled :) | 13:16.16 |
| chrisl | Cool. | 13:16.25 |
| | Antonio81: I just need to add the obligatory suggestion that you double check your usage against the license conditions | 13:17.21 |
| Antonio81 | i will do it, thanks :D | 13:32.50 |
