Public bug reported: I use pdftocairo as the default renderer in CUPS to print to my HP LaserJet printer. It's the tool that better manages PDF documents with shading and transparency (common in beamer presentations and PDFs generated by cairo). Everything worked fine until I discovered some pages in documents were incorrectly printed.
I tried to print a PDF document (produced by pdfTeX) containing the Helvetica-Narrow fonts, and some lines of the document exhibited wrong character spacing. I tried to print the same document using Chrome and the text was printed with correct spacing so the printer wasn't the responsible. After changing the default PDF->PS renderer I discovered the fault was in pdftocairo because any conversion with pdftops and pdf2gs resulted in correct character spacing on my screen. Changing the PS language level did not work. Also, this bug doesn't manifest when pdfTeX uses the URW base 35 fonts instead of the Adobe ones. I am attaching a PDF document that can be converted with pdftocairo, pdftops and pdf2ps with pdftocairo being the only one that looks different at the narrow fonts. ** Affects: cairo (Ubuntu) Importance: Undecided Status: New ** Attachment added: "PDF test case." https://bugs.launchpad.net/bugs/1790242/+attachment/5183198/+files/testcase.pdf -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cairo in Ubuntu. https://bugs.launchpad.net/bugs/1790242 Title: Converting PDF to PS with pdftocairo results in wrong character spacing with some Adobe fonts Status in cairo package in Ubuntu: New Bug description: I use pdftocairo as the default renderer in CUPS to print to my HP LaserJet printer.
