* A few special definitions used by the program that sends jobs to PostScript
* printers. Most, if not all the testing, was done on a QMS PS-800 printer.
*
* POSTBEGIN, if it's not NULL, is some PostScript code that's sent to the
* printer before any of the input files. It's not terribly important since the
* same thing can be accomplished in other ways, but it is convenient. POSTBEGIN
* is initialized so as to disable job timeouts. The string can also be set on
* the command line using the -P option.
*

/*
*
* Status lines returned by the printer usually look like,
*
*
* %%[ status: idle; source serial 25 ]%%
* %%[ status: waiting; source serial 25 ]%%
* %%[ status: initializing; source serial 25 ]%%
* %%[ status: busy; source serial 25 ]%%
* %%[ status: printing; source serial 25 ]%%
* %%[ status: PrinterError: out of paper; source serial 25 ]%%
* %%[ status: PrinterError: no paper tray; source serial 25 ]%%
*
*
* although the list isn't meant to be complete.
*
* The following constants are used to classify some of the different printer
* states. readline() reads status lines from ttyi and converts everything to
* lower case. getstatus() interprets the text that readline() stores in sbuf[]
* and returns integer codes that classify the printer status. Those codes are
* used in routines start(), send(), and done() to figure out what's happening
* and what should be done next.

* STATUS is used to initialize an array of type Status that translates the

* later on in the program. State strings should all be entered in lower case.
* readline() converts characters to lower before adding them to sbuf[]. If you
* add any states, do it in lower case only, and be sure to add the new status
* descriptions before the UNKNOWN entry. The lookup in getstatus() terminates
* when it finds the printer state or encounters an entry with NULL in the state
* field.
