Contact sheets. Am I asking too much from LR

in workflow need 'printed' contact sheets out asap public at, note file numbers, view on screen > purchase.

i have produced contact template 16up , on average print 10-18 sheets @ time.

the time takes print not viable (anything 2 minutes (rare) - 20 minutes, average 15 mins +)

i have set draft mode printing, increased ram 12gb (from 4)

and average file 3000 pixels.

i have set activity monitor (mac 10.8.4) watch , there seems no 'page outs'

and cpu , free space seem within limits.

i have tried pdf , jpeg file, seems take long.

also tried on lr3, lr4.4 & lr5 trial, no difference.

 

am asking of os or lr.

any input appreciated

thanks

 

p.s.

saw 1 or 2 other posts suggesting draft mode made massive difference big files, not mine.

pages seem load quick @ first, hang.

may imagination, time print seems increasing

after searching think may have found solution ?

we creating 1:1 previews editing photos before printing contact sheets.

the 1:1 previews seemed causing hold up.

 

so remedy this

in library > library menu > previews > discard 1:1 previews > photos

it printed out contact sheets @ fair rate of knots.

(i believe once go loupe , zoom in, creates 1:1 preview again)

22 pages 349 images ave. 3,500 pixels per photo = 12 seconds (compared 20 mins never),

obviously + printing time.

 

quick silly question though ??

i take if have minimal preview settings not infringe quality of larger printed copies ?

(i take it, that, preview ?)

 

i have thought lr have found solution before now

or @ least provided sort of info / tutorial / remedy.

looking @ results people having problems goes way lr2/lr3.
