I presume you meant /dev/ptyp* (r--) and /dev/ttyp* (r-x) for group and
user. Should they NOT be executable?
chmod 666 ptyp* and ttyp* gets me an rxvt (both BL3 and BL2) and they are
now all rw- and not executable.
I am never going to remember all this and should have been taking better

The SW7.1 gs 5.10 has the I/O permissions problem as user.
-rwxr-xr-x 1 root bin
chmod 4777 made it -rwsrwxrwx and now it works for user.
The one I compiled (8.50) works for user (in X).
(I may have chmod 4777 already?)

I used the same but .....-sOutputFile=- - < $1 > /dev/lp0.
My script works to print as root from CLI (outside of Opera).

Your line works as 'user' but not as 'root'. lpq - no entries
Same as if I were using lpr as root. Did it work for you as 'root' in
lpr is -r-s--s--x 1 root lp
It works for user not root.
chmod -s lpr: -r-x--x--x
This does not make it work as root and it stops if from working as 'user':
"Cannot create /var/spool/lpd/postscript/.seq"
There is a .seq there from 3 minutes ago with permissions:
lprm removes the active job (owner user) and .seq and a cf file.
/dev/lp0: crw-r--r-- (obviously user can print to it, suid?)
lpd: -rwxr--r-- (works only for root)
A BSD printing discussion suggested:
chmod 700 /usr/sbin/lpd
chmod 755 /usr/bin/lp* (lpq, lprm, lpr)
chmod 4755 /usr/bin/lpr
chmod 660 /dev/lp0
Do you want to test this?
I am afraid to completely mess up something that is now usable for 'root'
without lpr/lpd and for 'user' with them.
700 - user rwx
50 - group rx
5 - other rwx
660 rw for everyone except 'other' (root?) - for device files
777 rwx for everyone - for executables
666 rw for everyone
444 r for everyone
