I have done these tests. a lot of fiddling with the files was necessary because they all have to be owned by root to work.
The "old" ppd file produces draft, normal and high printouts as you would expect. The new PPD file produces draft and high output but normal just ejects a blank sheet. This has been the problem. I have tried fiddling with the print settings printing from chrome but I van not get any mark on the paper. Printing from libre Office Write is the same but in the print dialog as well as the two printers "oldppd" and "newppd" show up. If you select "oldppd" it prints correctly.
