Hi all
as far as i work with linux as a my desktop i have more questions 
so one more trouble with printing for meā¦
i have bad known printer canon lbp2900 this is not a problem it works fine (you need only official instructions but not ubuntu forum)
i was needed to print 73 pages document to both side of a paper
so i print one sideā¦ rotate it and put in printer to print otherā¦ i start to print all range but something go bad and it was printed only some pages 2-8ā¦
so i reload servicesā¦ and try one more from evince but now i needed to print from 9 to the end so i just press print button and set printing optins that i need range 9-73
then press preview buttonā¦ new window appear and now starts tangoā¦
count it seems display correctly but it seems can differents at 1 last pageā¦ first page display correctly (10) but second repet display 10 third repeat display 10 and so on till the end.
i test some timesā¦ all the same. but it prints correct.
