In csh (as opposed to bash) you can do exactly what you want.
alias print 'lpr \!^ -Pps5'
print memo.txt
The notation \!^ causes the argument to be inserted in the command at this point.
The ! character is preceeded by a \ to prevent it being interpreted as a history command.
You can also pass multiple arguments:
alias print 'lpr \!* -Pps5'
print part1.ps glossary.ps figure.ps
