The default for non MS-Windows systems is to simply use "lpr" to print the
file: >
system('lpr' . (&printdevice == '' ? '' : ' -P' . &printdevice)
. ' ' . v:fname_in) . delete(v:fname_in) + v:shell_error
system(['lpr']
+ (empty(&printdevice)?[]:['-P', &printdevice])
+ [v:fname_in])
. delete(v:fname_in)
+ v:shell_error
On MS-Dos and MS-Windows machines the default is to copy the file to the
currently specified printdevice: >
system('copy' . ' ' . v:fname_in . (&printdevice == ''
? ' LPT1:' : (' \"' . &printdevice . '\"')))
. delete(v:fname_in)
system(['copy', v:fname_in, empty(&printdevice)?'LPT1':&printdevice])
. delete(v:fname_in)
If you change this option, using a function is an easy way to avoid having to
