Fast fire function for PostScript printing.
If a region is active, the region will be printed instead of the whole buffer.
Also if the current major-mode is defined in `pr-mode-alist', the settings in
`pr-mode-alist' will be used, that is, the current buffer or region will be
printed using `pr-ps-mode-ps-print'.
Interactively, you have the following situations:
M-x pr-ps-fast-fire RET
The command prompts the user for a N-UP value and printing will
immediately be done using the current active printer.
C-u M-x pr-ps-fast-fire RET
C-u 0 M-x pr-ps-fast-fire RET
The command prompts the user for a N-UP value and also for a current
PostScript printer, then printing will immediately be done using the new
current active printer.
C-u 1 M-x pr-ps-fast-fire RET
The command prompts the user for a N-UP value and also for a file name,
and saves the PostScript image in that file instead of sending it to the
printer.
C-u 2 M-x pr-ps-fast-fire RET
The command prompts the user for a N-UP value, then for a current
PostScript printer and, finally, for a file name. Then change the active
printer to that chosen by user and saves the PostScript image in
that file instead of sending it to the printer.
Noninteractively, the argument N-UP should be a positive integer greater than
zero and the argument SELECT is treated as follows:
If it's nil, send the image to the printer.
If it's a list or an integer lesser or equal to zero, the command prompts
the user for a current PostScript printer, then printing will immediately
be done using the new current active printer.
If it's an integer equal to 1, the command prompts the user for a file name
and saves the PostScript image in that file instead of sending it to the
printer.
If it's an integer greater or equal to 2, the command prompts the user for a
current PostScript printer and for a file name. Then change the active
printer to that chosen by user and saves the PostScript image in that file
instead of sending it to the printer.
If it's a symbol which it's defined in `pr-ps-printer-alist', it's the new
active printer and printing will immediately be done using the new active
printer.
Otherwise, send the image to the printer.
Note that this command always behaves as if `pr-auto-region' and `pr-auto-mode'
are both set to t.
