In order to put this two tests(.generic and .epson) in bvt-cq to prevent regressions early, we have to stabilize them.

There is currently flaky output:
https://wmatrix.googleplex.com/testhealth/unfiltered?suites=bvt-perbuild&tests=platform_AddPrinter%2A&days_back=10&releases=64&hide_missing=True

Top fail rate(>10%) on kefka,ultima,stout,parrot,lulu

Reasons
- valid_config - Could not setup valid printer 3
- Command <cmp /tmp/printing_request.log /usr/local/autotest/tests/platform_AddPrinter/golden_printing_request_generic.bin> failed, rc=2, Command returned non-zero exit status
