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

This is useful if you have a bunch of images/scans where the same area at the top needs to be chopped.
Sometimes the -trim option (such as the case of white space on top)is wrong and ends up cropping the image and losing some text.
ImageMagick's convert is very useful but tricky to find some things out as I find it to be less than intuitive sometimes.

I believe from what I've read that this card's driver doesn't support the features after trying all known troubleshooting methods.

If the file size is too large you need to resize them on the fly:
convert -resize 25% *.jpg output.pdf
The resize flag takes a % I have tried without and it seems to take it as pixels and becomes way too small.
You can also play with the "-quality 25" flag to decrease file size even more.........
I've thought for awhile that Asus has been banking on its years old reputation for quality amongst gamers and enthusiasts and I think I'm right. My Asus VE247H Monitor with a supposed 2MS refresh rate has 1 red/stuck/dead pixel but fortunately it can only be seen on a non-true black picture or against a blue screen.
