I found a problem when using lastest printmig version from Microsoft: it doesn't handle drivers containing .cab files as stated by MS => http://blogs.technet.com/askperf/archive/2008/10/17/why-printmig-3-1-is-retired.aspx I had to sync print servers monthly and they had print drivers like HP P2015 (which contains cab file) so i looked into it. I found that MS excluded cab files in printmig there (see png there: http://img408.imageshack.us/img408/7798/printmig.png ) So one could replace one or more character there to avoid this problem although it is against the EULA.
