Bug#877888: cups-bsd: lpq and lp ignore the PRINTER environment variable

[Sanjoy Mahajan <sanjoy@olin.edu>]

Package: cups-bsd
Version: 2.2.4-7
Severity: normal
File: /usr/bin/lpq

lpq and lp are no longer paying attention to the PRINTER environment
variable.  (The cups(1) manpage says that PRINTER is used except for
setuid binaries.  But lpq and lp are not setuid.)

Here is a commented log with lpq:

  $ lpq         
  lj400 is ready  /* my default destination */
  no entries
  $ PRINTER=mh371 printenv PRINTER 
  mh371           /* to show that the environment variable inherits */
  $ PRINTER=mh371 lpq
  lj400 is ready  /* but lpq ignores it */
  no entries
  $ lpq -Pmh371
  mh371 is ready  /* to show that mh371 is a known destination */
  no entries

And for lp:

  $ PRINTER=mh371 lp /usr/share/hplip/data/ps/testpage.ps.gz
  request id is lj400-2890 (1 file(s))

It went to the default destination despite the environment setting.

Here is my /etc/cups/lpoptions:

Default lj400 fitplot=true PageSize=Letter sides=two-sided-long-edge
Dest lj400/gs fitplot=true PageSize=Letter pdftops-renderer=gs sides=two-sided-long-edge
Dest mh235 fitplot=true PageSize=Letter sides=two-sided-long-edge
Dest mh271 fitplot=true PageSize=Letter sides=two-sided-long-edge
Dest mh271/duplex fitplot=true PageSize=Letter sides=two-sided-long-edge
Dest mh271/saver fitplot=true number-up=2 PageSize=Letter sides=two-sided-long-edge
Dest mh371 PageSize=Letter sides=two-sided-long-edge
Dest mitx duplex=duplexnotumble
Dest psc outputorder=reverse PageSize=Letter PrintoutMode=High
