13. How to print to a fax machine.

13.1.1. Faxing from PDQ

PDQ doesn't ship with a fax interface declaration, but here's a simple one (which is only partly tested):

interface efax-0.1 { help "This interface uses the efax package's fax program to send a fax. You should first get efax's \"fax send\" working by itself by editing the file /etc/efax.rc and testing. Connect this interface to a generic postscript driver to define a fax machine \"printer\"". requires { "efax" "fax" } # Making phone number required means that the add printer wizard # will demand a phone number at add printer time. This is # undesirable, so it isn't explicitly required, even though it is # logically required. The send_exec script checks for the number. # You could skip the wizard by adding this printer by hand to # .printrc, mark this as required, and it might then prompt? argument { var = "PHONE_NUMBER" desc = "Phone Number" help = "The phone number to dial. Prefixes like 9 ought to be defined in your /etc/efax.rc file." } option { var = "RESOLUTION" desc = "Fax resolution" default_choice = "high" choice "low" { value = "-l" desc = "Low" help = "Low resolution on a fax is 96lpi." } choice "high" { value = "" desc = "High" help = "High resolution on a fax is 192lpi." } } # If you don't specify a phone number the job just fails, and # the only way to figure this out is to look at the error message # at the bottom of the job details. Hmm. send_exec { if [ "x$PHONE_NUMBER" != "x" ] then fax send $RESOLUTION $PHONE_NUMBER $INPUT else echo 'You must specify a phone number!' false fi } }
