On Linux Mandrake 7.0 and npadmin version 0.8.4 (rpm package), I have a problem with an external print server HP JetDirect 170X connected with a lexmark e310 printer
for :
npadmin --vendor ip_hpjd170
vendor="HP";
it's Ok.
for :
npadmin --display ip_hpjd170
npadmin: ber.C:229: int BerString::copy(char *, unsigned int): the assert 'len>stringlen+1' has failed
it's no OK, same for --model option, I have not tested other options
