FYI the smb.conf snippet for the fake printer I used:

[C250]
path = /var/tmp/c250raw
guest ok = Yes
printable = Yes
printing = sysv
print command = /usr/bin/true
lpq command = /usr/bin/ls /var/tmp/c250raw
lprm command = /usr/bin/true
lppause command = /usr/bin/true
lpresume command = /usr/bin/true
queuepause command = /usr/bin/true
queueresume command = /usr/bin/true
