Hmmm. And how does this differ from what happens in Cygwin when GV sends PDF to a printer via LPR? >> I'm pretty sure that this printer (Dell A10) is not a Postscript printer, so >> the PDF is not being translated into PS. > > That has no connection.

Still something I am not getting: 1. GV under Cygwin can display the PDF fine. That's what GV is meant to do -- be a viewer for PDF/PS. 2. GV has a print capability. By default, it (seems to) uses LPR for the printout mechanism. Therefore, if #2 ever works, then there must be an assumption about how it works that works for most (all?) printers. What is that assumption? >> As I understand it, the job of the printer driver >> is to forward the data sent by the application to the printer >> (ie. manage the hardware).

Your question has no simple answer. Undoubtedly. Under Adobe, the print capability works whereas, under GV, it doesn't seem to work. I still do not have a means of determining why. > WBR, > Andrey Repin (anrdaemon@yandex.ru) 01.07.2014, <20:05> -- David Masterson Programmer At Large -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
