If you can print other PDFs but not a particular one it is very likely that the PDF size is A4 (the longer, skinnier Asian paper size) instead of the North American letter size ( 8.5" x 11"). This breaks printing in most cases. Or it may print if you find a program that ignores the size issue.
Here is an example of an A4 being rejected by a printer in Ubuntu Linux via CUPS
Cannot print PDF CUPS Samsung C460:
You'll have to edit the policy.xml file to fix this:
convert -density 300 output.pdf agreement.jpg
convert.im6: not authorized `output.pdf' @ error/constitute.c/ReadImage/454.
convert.im6: no images defined `agreement.jpg' @ error/convert.c/ConvertImageCommand/3044.
sudo vi /etc/ImageMagick*/policy.xml
A very handy feature of ImageMagick's convert command is that it can convert PDF's to other image formats like jpg but did you know you can even manually select a range or specific pages from the PDF?
Here is an example of converting a range of pages from a PDF in this case pages 25 to 36:
convert -density 300 "vSphere 6.5-1.pdf[25-36]" vsphere.jpg
Here is an example of converti........
It is a common issue and here is the solution (increase the density/dpi):
convert -density 120 some.pdf output.jpg
You will need to play with the density setting to get the perfect file size and resolution.
If you want a smaller file you can always use the "-quality" switch and eg. -quality 25 would be 25%/100 quality........
convert -density 200 file.pdf file.jpg
Increase the "density" value to get a higher resolution/larger file an decrease it to go smaller.
This is really the quickest and simplest way.........
convert -density 400 somepdf.pdf -scale 2000x1000 output.jpg
The key is the "-density 400" switch and also -scale 2000x1000

That was the perfect solution when I was frustrated with how small the resulting JPG's resulted. I'm sure this will help a lot of people when it comes time to converting a PDF to JPG which I'm amazed Imag........
