Thank you for so many people give me the answer most of them are
correct. I just ist one of solution:
global]
printing = bsd
printcap name = /etc/myprintcap
load printers = yes
print command = lpr -P%p %s
lpq command = lpq -P%p
lprm command = lprm -P%p %j
where /etc/myprintcap looks like
r|Research Printer
a|Admin Printer
c|Computing Printer
north|North Campus
p|Publications Printer
