wallbroken | hi | 07:00.20 |
ghostbot | Welcome to #ghostscript. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. If you are looking for help or infomation about MuPDF, try the new #mupdf channel. | 07:00.20 |
wallbroken | i want to ask you if is there some way to check if my printer driver are GDI or not | 07:00.43 |
| my printer supports GDI, and PCL PostScript in emulated mode | 07:01.04 |
| i want to ask you if is there some way to check if my printer driver are GDI or not | 10:34.32 |
| my printer supports GDI, and PCL PostScript in emulated mode | 10:34.33 |
chrisl | wallbroken: If there isn't anything in the driver settings that gives a hint, your best bet is to print something to a file, and open the file in a text editor - if it looks like Postscript, it's probably Postscript (something like "%!PS-Adobe-3.0" in the early part of the file) | 11:05.29 |

| chrisl ^ | 11:13.37 |
chrisl | Yes?? | 11:14.26 |
wallbroken | those are two prints to a file | 11:14.46 |
| can you check please? | 11:14.50 |
chrisl | Well, given that the second line in both those says: "@PJL ENTER LANGUAGE = POSTSCRIPT" - I'd think that was a good hint | 11:15.30 |
wallbroken | chrisl, but in my case, PCL and POSTSCRIPT are emulated languages | 11:17.31 |
| the native language is GDI | 11:17.39 |
| why i can't see anything about GDI? | 11:17.49 |
| http://support.brother.com/g/b/spec.aspx?c=us_ot&lang=en&prod=mfc7820n_all | 11:18.03 |
| Print LanguageWindows® GDI | 11:18.09 |
| EmulationPCL 6 & BR-Script 3 | 11:18.14 |
chrisl | They are termed "emulated" because it's not Adobe Postscript, nor HP PCL | 11:18.25 |
wallbroken | and what about GDI? | 11:18.48 |
chrisl | What about GDI? | 11:18.56 |
wallbroken | Print Language: Windows® GDI | 11:19.06 |
| that's from my printer's datasheet | 11:19.13 |
chrisl | "GDI" is just a raster image format | 11:19.33 |
wallbroken | what does it mean? | 11:20.05 |
| can you speak more clearly? | 11:20.11 |
chrisl | GDI means Graphical Device Interface | 11:20.44 |
wallbroken | I know | 11:20.56 |
| but what's the answer to my question? | 11:21.04 |
chrisl | Your printer driver is producing Postscript | 11:21.30 |
wallbroken | Print Language: Windows® GDI | 11:22.57 |
| what about this? | 11:23.00 |
chrisl | Your driver is not producing GDI output | 11:23.28 |
wallbroken | why? | 11:23.36 |
chrisl | Because it's a Postscript printer driver, I would think | 11:23.52 |
wallbroken | http://support.brother.com/g/b/spec.aspx?c=us_ot&lang=en&prod=mfc7820n_all | 11:24.05 |
| please, see this link | 11:24.09 |
| Print Language: Windows® GDI | 11:24.17 |
| you are understanding the point? | 11:24.23 |
| i think not | 11:24.28 |
chrisl | No, not even slightly | 11:24.36 |
wallbroken | ok, get back again | 11:24.50 |
| each printer got some printing language | 11:25.03 |
| in my case there are 3 languages | 11:25.11 |
| one native languace called "GDI" | 11:25.20 |
| and some other emulated languages called "PCL, PostScript" | 11:25.38 |
| i tried all the driver the vendor is distributing | 11:25.54 |
| i printend to a file with both of them | 11:26.07 |
| and i get PCL or PostScript | 11:26.27 |
| so, i'm not understanding why i do not get GDI | 11:26.47 |
| which should be the main language of my printer | 11:26.57 |
chrisl | Well, surely that's a question for Brother tech support? It's certainly no a Ghostscript question | 11:27.55 |
wallbroken | no, it's a question about printing languages | 11:29.13 |
| if the driver was GDI and i print to a file, i will get some GDI language text? | 11:29.45 |
chrisl | GDI is, basically, a binary image format | 11:30.16 |
| https://en.wikipedia.org/wiki/Graphics_Device_Interface#GDI_printers is a decent description | 11:31.42 |
wallbroken | chrisl, already read it | 11:31.59 |
| i read all about 5 - 6 google results | 11:32.14 |
| for my questions, there is no answer over google | 11:32.29 |
chrisl | Unless I'm still not understanding, your question is why you are getting Postscript or PCL (rather than GDI) from your Bother printer's driver | 11:33.27 |
wallbroken | yes | 11:33.53 |
chrisl | Which sounds like a question that should go to Brother | 11:34.55 |
wallbroken | you have something with GDI driver? | 11:35.14 |
| i want to see how looks "print to a file" | 11:35.29 |
| with gdi driver | 11:35.32 |
chrisl | It'll be binary | 11:35.45 |
| FWIW, my printer does not seem to support GDI | 11:39.23 |
wallbroken | chrisl, is there a free software for windows to open postscript files? | 11:41.05 |
chrisl | Ghostscript - the subject of this channel..... https://ghostscript.com/ | 11:41.35 |
wallbroken | why some PDF printer needs ghostscript? | 11:42.43 |
| ? | 11:42.50 |
chrisl | PDF printers work by installing a Postscript printer, capturing the Postscipt, and using Ghostscript to convert the Postscript into PDF | 11:43.24 |
| Well, some using solutions other than Ghostscript, but same idea | 11:43.48 |
wallbroken | and why there is not a native pdf printer? | 11:46.11 |
| pdf is at the same level of ps | 11:46.20 |
chrisl | What would be the advantage? A lot of work, for the same result | 11:46.56 |
wallbroken | and why printers use postscript instead of pdf? | 11:47.50 |
| (phisical printers) | 11:48.04 |
chrisl | The main reason is that Postscript is streamable, and has lower resource requirements, so the printers can be cheaper | 11:48.34 |
wallbroken | i'm trying ghostscript to open .ps, but is so rude viewer, no way to zoom, pan, select... | 11:48.46 |
chrisl | wallbroken: you might be more comfortable with http://gsview.com/ | 11:49.43 |
wallbroken | i installed it | 11:55.06 |
| but i don't find it in quick start | 11:55.14 |
chrisl | gsview isn't something I work on, so I can't really help | 11:56.10 |
wallbroken | how could be the output to be accepted by the printer in gdi? | 12:01.12 |
| raw ? | 12:01.23 |
chrisl | Sorry, I don't understand the question | 12:02.13 |
wallbroken | if i get a .pcl file and upload it to the printer via ftp, it will be printed correctly. | 12:03.05 |
| can i do the same by the GDI language? | 12:03.19 |
chrisl | It's entirely dependent on the specific printer. Probably not via ftp though, for any printer | 12:04.23 |
