If you have redirected printers and selected "Show printer selection dialog on each print", the print selection dialog will appear on print. However, there will be no actual printing output. I believe this is caused by this bug: http://code.google.com/p/sumatrapdf/issues/detail?id=1642
Just tried to drop in replace version 1.7 with 2.2.1 of sumatrapdf, basic test on a Windows 7 works great.
Tested to print edos document attached to upstream issue without any problems, so there is no regressions with bug #3933, #3441 http://code.google.com/p/sumatrapdf/issues/detail?id=1331
Verified that there was no regression with #3956 the new sumatrapdf still respects the restrictions in our shipped sumatrapdfrestrict.ini. The 'Check for updates' is not available on help menu.
Commit r27283 updates sumatrapdf from v1.7 to v2.2.1
Works great.
