Post subject:  PDF Prints too large when printed via Chrome built in Viewer
Hi,

I have a bug report to fix, where when a PDF I generate using PDFSharp/MigraDoc prints (to paper) at about 200% scale, meaning the printed pages only have the top left quarter of the page on them.

This is only a problem in Chrome (i.e. not FF or IE), and if I disable Chrome's built in viewer plugin, and use the Adobe Reader plugin instead, it prints fine (or if I save the pdf to a file and open in Adobe Reader then print). I have tried different settings in the Chrome print dialog, to no avail, though the options are very limited.

I have also printed other PDFs from Chrome's default PDF viewer ok (although not all of them).

Is there something missing in the PDF header or something else I could change/add to get around this problem?

If there isnt a known solution, I plan to browser sniff Chrome and output the PDF to the page via a Save As prompt, rather than inline, which I believe should cause the PDF to always open in Adobe Reader (if the users have it installed, which they should) to get around this, but I would prefer to keep it all displaying inline x-browser.

Thanks,

Mike

I don't like the standard support answer ("This is not a problem of our software."), but I think this is most likely a Chrome problem.
Probably PDFsharp could be changed as a workaround - if we knew what causes Chrome to print at the wrong size.

Is it exactly 200%? Or roughly factor 2?

I just printed two test pages, created with PDFsharp, with Chrome - and both pages look correct.
This leads to another standard support answer: "We cannot replicate the problem."

Print looks correct, page preview also looked correct.

Does the page preview look correct when the prints fail? Maybe a problem with the Chrome settings or the printer settings?
Would you provide a (ZIPped) PDF that prints incorrectly when you print it?

Weekend begins in 25 minutes and further investigation may have to wait till Monday.

Hi,

I actually just fixed this problem by setting the page orientation to Portrait (it was defaulting to portrait before I believe).

Thanks for the quick response though!
