this code is not yet written

Works for me, OS X 10.13.4 on 20180518. Copied gzip directly to /Library/Printers/PPDs/Contents/Resources and renamed to ‘HP DesignJet 755cm.gz’

Selected with JetDirect card & protocol. After print completed (looks good, color from Fusion360 demo sheet size B), there was about a ‘C’ sized drawings worth of blank, followed by text indicating “Error Undefined, OFFENDING COMMAND: Stack”

Thanks, would like to improve it too…tried with Windows drivers and Parallels multiple times. You’ve saved my DesignJet Thanks.

Thanks for posting this. I’ve been searching for this PPD for quite a while. Did you did it out of an Adobe set per chance?

Yep, I ran into the same issue last week. There is an open ticket to track it: https://bugs.launchpad.net/qemu/+bug/1336794

Hey I am so excited I found your wegbape, I really found you by error, while I was searching on Askjeeve for something else, Anyhow I am here now and would just like to say thank you for a marvelous post and a all round thrilling blog (I also love the theme/design), I done28099t have time to go through it all at the moment but I have bookmarked it and also added in your RSS feeds, so when I have time I will be back to read a great deal more, Please do keep up the awesome work.
I needed to cmoopse you one very small remark to be able to say thanks a lot again on the wonderful tricks you've featured in this case. It has been really strangely open-handed of people like you to make unhampered just what numerous people would've supplied as an electronic book to get some dough for themselves, most importantly considering the fact that you might well have done it if you wanted. These inspiring ideas also acted to become a great way to understand that some people have similar fervor similar to my very own to learn a whole lot more with regard to this issue. I am sure there are lots of more enjoyable periods in the future for folks who discover your blog.
For anyone else who stumbles across this, I found a better solution: http://www.marmottus.net/blog/2012/03/25/nginx-and-lua/
Very strange indeed.  I still don't understand why every Lua implementation (except for luasp.org) seems to be done backwards. Why doesn't anyone try to take the php approach and allow web designers to work on designing instead of doing strange script-fu just to use Lua?
unfortunately JPEGInfo will not catch all.

the tool above catches the rest
I found a much simpler solution, there is a tool 'Corrupt JPEG Checker' for Mac OSX.
It can be found here: http://www.failedinsider.com/corruptjpegcheckermacosx/ or in the mac app store.

Saved me a lot of time.


I realise you did this 2 years ago now, but this is really awesome. I'm a bit surprised there's not more attention drawn to:
  • adding transparency to the JPEG specification in a standards-based way and
  • your stop-gap solution.
This may certainly come in handy for some client one day, thank you for exploring this and developing tools for us to use even!

Just curious though, why are you using uncompressed PNGs for the alpha channel?  It would seem to me that embedding a grey-scale JPEG layer into the original JPEG would yield a much more compact solution and the benefits and pitfalls of lossfully compressing the alpha-channel should be very understood by the wielder of this solution.

Given the apparent intelligence reflected in your posts, it is obvious to me that you had already considered this, but yet you went with embedding a PNG into a JPEG.  Do you have a post somewhere that details your logic here?  If you're not interested in blogging about it, please drop a note at 'm' followed by 'j' followed by 'k' at sisuconsulting.com.  Many, many thanks in advance!
