You've gotten 17 ifs in your code snippet but 11 fis only, so I guess there sth. wrong with those. Taking a closer look, the if [ "$response" != "yes" ] seems to be missing one, but, more related to the syntax error that you quote, every if [ "$option-oki"...] has an unterminated if - elif - elif construct in it, which will bother bash if it reaches the esac statement. Pls correct and come back with the result.
BTW, did you consider bash's select statement to offer and read a selection? And, I'd prefer to put the respective options every printer offers into an option file that you can print out for selection and that you can easily adapt should a new printer model come in. Plus, why don't you collect e.g. all three-tray-printers into one single question (option_OKI between 1 and 6 -> ask for tray) and generate the printer driver name from the few variables read in answer?

backend(1) Easy Software Products backend(1)
NAME
backend - cups backend transmission interfaces
SYNOPSIS
backend job user title num-copies options [ filename ]
DESCRIPTION
The CUPS backend interface provides a standard method for sending document files to different physical interfaces.
Backends must be capable of reading from a filename on the command-line or from the standard input, copying the standard input to a tempo-
rary file if required by the physical interface.
The command name (argv[0]) is set to the device URI of the destination printer.
ENVIRONMENT VARIABLES
The following environment variables are defined by the CUPS server when executing the backend:
CHARSET
The default text character set (typically us-ascii or iso-8859-1).
CLASS
When a job is submitted to a printer class, contains the name of the destination printer class. Otherwise this environment variable
will not be set.
CONTENT_TYPE
The MIME type associated with the file (e.g. application/postscript).
CUPS_DATADIR
The directory where data files can be found.
CUPS_SERVERROOT
The root directory of the server.
DEVICE_URI
The device-uri associated with the printer; this is provided for shell scripts which may not be able to get the passed argv[0] string.
LANG
The default language locale (typically C or en).
PATH
The standard execution path for external programs that may be run by the backend.
PPD
The full pathname of the PostScript Printer Description (PPD) file for this printer.
PRINTER
The name of the printer.
RIP_CACHE
The recommended amount of memory to use for Raster Image Processors (RIPs).
SOFTWARE
The name and version number of the server (typically CUPS/1.1).
TZ
The timezone of the server.
USER
The user executing the backend (typically lp).
