The customer reports and I've verified that Ghostscript cannot read the attached PDF file, producing a "Error: /rangecheck in --run--" error. All version of Ghostscript that I tried, from 8.53 to head (5091054103f3b07bbae8ab2fc75e6c6cc3fd7a86) produce the same error. Apple Preview 5.0.3 as well as Acrobat 8.2.6, 9.4.4, and 10.0.3 read the file without problem, mupdf produces an error (see separate mupdf bug for details). The command line I'm using for testing: bin/gs -sDEVICE=ppmraw -o test.ppm ./Origina.pdf The customer reports: Looking the content of this PDF file, it appears that it makes use of a very uncommon xref encoding but which matches the PDF Reference

As of 45bf62dc4e7271c25ee53e1e2ce0de51955132de this file now works in mupdf: pdf_repair.c: Skip first comment after version marker. Some particularly broken generators forget to terminate the comment with a newline. Skip the comment character so we'll get some garbage tokens that we can ignore, rather than consuming the innocent objects that follow on the same line as the %.
Ghostscript can run the file if "xref 0 837 0000000000 65535 f 0000124513 00000 n ..." is replaced with "xref 0 837" "0000000000 65535 f 0000124513 00000 n ..." Of course, xref should be terminated by a new line but gs can handle this. The sample file produced by "pcl convert 2.10" is full of bugs. Perhaps, there are better tools to convert PCL to PDF.
Created attachment 7486 [details] patch Accept and skip any number of whitespace characters (including just spaces) after the entry count in the xref table. Remove /lineeq and /linene procedures that are no longer used.
The patch has been committed as a rev. 2f0b609805f1abf42b4b10dd721d9fef3001a847
