hello

My question is whats the difference between LP and LPR to print Sun Solaris ?

lp -dprintername postscriptfile.ps

or

lpr -Pprintname postscriptfile.ps

lp send requests to a local printer from a Solaris host.

For SunOS it's lpr.

Obviously they're both present on current OS, but it's good practise to use the correct one incase you end up using an older version of Solaris.

lpr is the off-line printer... lp is just a frontend to the lpr. (that is in FreeBSD, maybe is the same in Sun Solaris), out put from man lp(1):


LP(1) FreeBSD General Commands Manual LP(1)

NAME
lp -- front-end to the print spooler

SYNOPSIS
lp [ -cs ] [ -o option ] [ -d printer ] [ -n num ] [ name ... ]

DESCRIPTION
The lp utility is a front-end to the print spooler as required by the
IEEE Std 1003.2 (``POSIX.2'') specification. It effectively invokes
lpr(1) with the proper set of arguments.
