I use Ubuntu 12.04, CUPS 1.5.2-bzr2 and TurboPrint 2.25-1.
Printer is connected to Welland USB_Server (with PrintServer by LPD_only and announced services by Avahi). TurboPrint autodetected printer and add to printer list. I tried printing TestPage by toolbox panel, but it was very slow 1 lines by 20 minutes, so i canceled a job. Next i tried do the Nozzle Check, and this was printed very fast. When i print on Windows everything is ok.
What can be a reason?
