Re: In Squeeze replacing python version 2.6.6-13~bpo60+1 with version 2.6.6-3+squeeze7
python-dev isn't required to set up printing. That can be done using
http://localhost:631 or with lpinfo plus lpadmin.
In general: Some additional info on setting up printers;
CUPS can use vendor-supplied PPD files for Postscript printers directly.
Often these come with the Windows drivers for a printer, or can be found
on the printer vendor's website.
If you are thinking of buying a new printer, get one with postscript
support. It makes things a lot easier.
