Good day. Here we use Firefox 62 / Ubuntu 16.04 on several machines, and the processed print job file as it is sent to CUPS by pdf.js is very large compared to the original or a print job file processed by the default document viewer or even on Firefox for Windows. This drives me nut because in large documents send by 5, 6 or more machines, print server hangs up and I really haven't a clue that what happens. I can disable pdf.js and open the files with default PDF reader, but I really want to use pdf.js because is much more handy.

Any idea will be much apreciated.
