Re: [Printing-architecture] PAPPL 1.2rc1 (Supply levels)

Thank you very much, Mike!

It works now!

I have done the same implementation as with hp-printer-app in 
pappl-retrofit now and I get supply levels! At least if I use one of 
PAPPLs own backends (and not embedded CUPS backends) and network printers.

Later on I will see how to do it with the CUPS backends (they are custom 
scheme "cups:", any hints welcome) and also whether one can use 
hp-levels of HPLIP in the HPLIP Printer Application so that there one 
can also get supply levels of USB printers.
