Yes i *know* file is usually Windows, but i wonder if there is a program, that will open and convert this type of file to something , or even. If you have many files to convert, set up Ghostscript batch jobs with GoBatchGS. can anyone tell me how to convert file to a pdf (for free) in windows 7? the PRN (PostScript) file to your home PC, convert it to PDF using Ghostscript or. There are also a number of utility scripts for common to convert a PostScript document to PDF: ps2pdf The output is saved as There are other.

For other information, see the Ghostscript overview and, if necessary, how to install Ghostscript. This gjostscript describes how to use the command line Ghostscript client. Ghostscript is also used as a general engine inside other applications for viewing files for example.

Please refer to the documentation for those applications for using Ghostscript in other contexts. The command line to invoke Ghostscript ghoztscript essentially the same on all systems, although the name of the executable program itself may differ among systems. For instance, to invoke Ghostscript on unix-like systems type:. There are other utility scripts besides ps2pdfconvwrt pdf2psps2epsi ghostsrcipt, pdf2dscps2asciips2ps and ps2ps2. These just call Ghostscript with the appropriate if complicated set of options.
You can use the ‘ps2’ set with eps files. The interpreter reads and executes the files in sequence, using the method described under ” File searching ” to find them. The interpreter runs in interactive mode by default. After processing the files given on the command line if any it reads further lines of PostScript language commands from the primary input stream, normally the keyboard, interpreting each line separately.
To quit the interpreter, type ” quit “. The interpreter also quits gracefully if it encounters end-of-file or control-C. The interpreter recognizes ghostscriot options. An option may appear anywhere in the command line, and applies to all files named after it on the line.
The most important are described in detail here. Please see the reference sections on options and devices for a more complete listing.
You can get a brief help message by invoking Ghostscript with the comvert or -?
Ghostscript has a notion of ‘output devices’ which handle saving or displaying the results in a particular format. Ghostscript comes with a diverse variety of such devices supporting vector and raster file output, screen display, driving various printers and communicating with other applications.
If this option isn’t given the default device usually a display device is used. For complete description of the devices distributed with Ghostscript and their options, please see the devices section of the documentation.
Note that this switch must precede the name of the first input file, and only its first use has any effect. You can set the output device and process a file from the interactive prompt as well:.
All output then goes to the Epson printer instead of the display until you do something to change devices.
You can switch devices at any time by using the selectdevice procedure, for instance like one of these:. Some printers can print at several different resolutions, letting you balance resolution against printing speed. To select the resolution on such a printer, ghostcript the -r switch:. Where the two resolutions are same, as is the common case, you can simply use -r res.
The -r option is also useful for controlling the density of pixels when rasterizing to an image file. It is used this way in the examples at the beginning of this document. Ghostscript also allows you to control where it sends its output.
How to Convert a PRN File to PDF
With a display device this isn’t necessary as the device handles presenting the output on screen internally. Some specialized printer drivers operate this way as well, but most devices are general and need to be directed to a particular file or printer. For instance, to direct all output into the file ABC.
On Unix and VMS systems it normally goes to a temporary file which is sent to the printer in a separate step. When using Tl as a file rasterizer converting PostScript or PDF to a raster image format you cpnvert of course want to specify an appropriately named file for the output.
Ghostscript also xonvert the special filename ‘ – ‘ which indicates the output should be written to standard output the command shell. Note, some devices e. For example, in order to create two PDF files from a single invocation of ghostscript the following can be ghostscriph.
Specifying a single output file works fine for printing and rasterizing figures, but sometimes you want images of each page of a multi-page document. Gghostscript can tell Ghostscript to put each page of output in a series of similarly named files.
The format specifier is of a form similar to the C printf format. The general form ggostscript is:. For more information, please refer to documentation on the C printf format specifications. Note, however that the one page per file feature may not supported by all devices. Also, since some devices write output files when opened, there may be an extra blank page written pdfwrite, ps2write, eps2write, pxlmono, pxlcolor, As noted above, when using MS Windows console command.
As a convenient shorthand you can use the -o option followed by the output file specification as discussed above. This is intended to be a quick way to invoke ghostscript to convert one or more input files. Ghostscript is distributed configured to use U. There are two ways to select other paper sizes from the command line:. Individual documents can and often do specify a paper size, which takes precedence over the default size.
The default set of paper sizes will be included in the currentpagedevice in the InputAttributes dictionary with each paper size as one of the entries. The last entry in the dictionary which has numeric keys is a non-standard Ghostscript extension type of PageSize where the array has four elements rather than the standard two elements.
This four element array represents a page size range where the first ghostscriipt elements are the lower bound of the range and the second two are the upper bound. By default these are [0, 0] for the lower bound and tk fffff, 16 fffff] for the upper bound. For actual printers, either the entire InputAttributes dictionary should be replaced or the range type entry should not be included. Using this option will result in automatic rotation of the document page if the requested page size pfn one of the default page sizes.
This allows the -dPSFitPage option to fit the page size requested in a PostScript file to be rotated, scaled and centered for the best fit on the specified page. See the ghostscrlpt on finding files for details. For a4 you can substitute any paper size Ghostscript knows. On Windows and some Linux builds, the default paper size will be selected to be a4 or letter depending on the locale. As noted above, input files are normally specified on the command line.
PRN to PDF API.
However, one can also “pipe” input into Ghostscript from another program by using the special file name ‘ – ‘ which is interpreted as standard input. When Ghostscript finishes reading from the pipe, it quits rather than going into interactive mode. Because of this, options and files after the ‘ – ‘ in the command line will be ignored. On Unix and MS Windows systems you can send output to a pipe in the same way. For example, to pipe the output to lpruse the command.
In this case you must also use the -q switch to prevent Ghostscript from writing messages to standard output which become mixed with the intended output stream. The example above would become. In the last case, -q isn’t necessary since Ghostscript handles the pipe itself and messages sent to stdout will be printed as normal. All the normal switches and procedures for interpreting PostScript files also apply to PDF files, with a few exceptions.
This is useful for creating fixed size images of PDF files that may have a variety of page sizes, for example thumbnail images. Annoation types listed in this array will be drawn, whilst those not listed will not be drawn.
To use this feature: For example, adding the follow to the command line: The list of pages should be given in increasing order, you cannot process pages out of order and inserting higher numbered pages before lower numbered pages in the list will generate an error. The PDF interpreter and the other language interpreters handle these in slightly different ways.
Because PDF files enable random access to pages in the document the PDF inerpreter lrn interprets and renders the required pages. PCL and PostScript cannot be handled in ths way, and so all ghostsceipt pages orn be interpreted. However only the requested pages are ghostscirpt, which can still lead to savings in time. Because the PostScript and PCL interpreters cannot determine when a document terminates, sending multple files as input on the command line does not reset the PageList between each document, each page in the second and subsequent documents is treated as following on directly from the last page in the first document.
The PDF interpreter, however, does not work this way. The PostScript interpreter, by contrast, would only render pages 1 and 2 from the first file. This means you must exercise caution when using this switch, and probably should not use it at all when processing a mixture of PostScript and PDF files on the same command line. Occasionally you may try to read or print a ‘PDF’ file that Ghostscript doesn’t recognize as PDF, even though the same file can be opened and interpreted by an Adobe Acrobat viewer.
In many cases, this is because of incorrectly generated PDF. Acrobat tends to be very forgiving of invalid PDF files. Ghostscript tends to expect files to conform to the standard.
In the past, Ghostscript’s policy has been to simply fail with an error message when confronted with these files. This policy has, no doubt, encouraged PDF generators to be more careful.

However, convdrt now recognize that this behavior is not very friendly for people who just want to use Ghostscript to view or print PDF files. Our new policy is to try to go broken PDF’s, and also to print a warning, so that Ghostscript is still useful as a sanity-check for invalid files. If you provide PDF ghostcsript standard input using the special filename ‘ – ‘Ghostscript will copy it to a temporary file before interpreting the PDF. Encapsulated PostScript EPS files are intended to be incorporated in other PostScript documents and may not display or print on their own.
