Trouble adding a printer with lpadmin I'm trying to add a printer through the Terminal using lpadmin, and it absolutely refuses to work. The printer adds just fine, everything looks perfect from what I can see, but any attempt to print results in a "Printer did not respond" error.

Here's the line I'm using to add the printer:

lpadmin -p _1BIT_16x09 -D 1BIT_16x09 -L "Export" -o printer-is-shared=false -E -v lpd://10.96.99.60/1BIT_16X09 -P ~/PPDs/_1BIT_16x09.ppd


The reason the -p name has a _ in front of it is because if I add it normally, it adds this, I'm assuming because the name starts with a number. I have crafted it to create the printer to appear exactly the same way within the cups web interface and the /etc/cups/printers.conf file.

If I add the printer using the above command (which doesn't work), this is what I get in printers.conf:

&lt;Printer _1BIT_16x09&gt;

&lt;/Printer&gt;


If I add it normally through the GUI (which does work), this is what I get:

&lt;Printer _1BIT_16x09&gt;

&lt;/Printer&gt;


As far as I can tell, aside from the UUID they are identical, but one works and the other doesn't. It's driving me bonkers. Any ideas?
The problem, embarrassingly enough, turned out to be an uppercase letter in the lpadmin command I was using.
