Non-printable characters
I have been using OKI data Microline printers; models 590 and 591 to print a bar code using the following escape sequence:
\E^PA^H^C00^D^C^A^A^A\E^PB^H
The escape sequence is stored in a unix file which is edited using vi.
Now, we are considering Microline printer model 395C and the bar code does not print using the same escape sequence.
Will someone please confirm that I have the correct syntax for using non-printable characters. In particular, I the ^C00. I read somewhere that the null character is ^@.
Any comments or suggestions will be appreciated.

I need to check ftp'd incoming files for characters that are not alphanumeric,<tab>, <cr>, or <lf> characters. Each file would have 10-20,000 line with up to 3,000 characters per line.

lpstat(1) Apple Inc. lpstat(1)
NAME
lpstat - print cups status information
SYNOPSIS
lpstat [ -E ] [ -H ] [ -U username ] [ -h hostname[:port] ] [ -l ] [ -W which-jobs ] [ -a [ destination(s) ] ] [ -c [ class(es) ] ] [ -d ]
[ -o [ destination(s) ] ] [ -p [ printer(s) ] ] [ -r ] [ -R ] [ -s ] [ -t ] [ -u [ user(s) ] ] [ -v [ printer(s) ] ]
DESCRIPTION
lpstat displays status information about the current classes, jobs, and printers. When run with no arguments, lpstat will list jobs queued
by the current user.
OPTIONS
The lpstat command supports the following options:
-E
Forces encryption when connecting to the server.
-H
Shows the server hostname and port.
-R
Shows the ranking of print jobs.
-U username
Specifies an alternate username.
-W which-jobs
Specifies which jobs to show, completed or not-completed (the default). This option must appear before the -o option and/or any
printer names, otherwise the default (not-completed) value will be used in the request to the scheduler.
-a [printer(s)]
Shows the accepting state of printer queues. If no printers are specified then all printers are listed.
-c [class(es)]
Shows the printer classes and the printers that belong to them. If no classes are specified then all classes are listed.
-d
Shows the current default destination.
-h server[:port]
Specifies an alternate server.
-l
Shows a long listing of printers, classes, or jobs.
-o [destination(s)]
Shows the jobs queue on the specified destinations. If no destinations are specified all jobs are shown.
-p [printer(s)]
Shows the printers and whether or not they are enabled for printing. If no printers are specified then all printers are listed.
-r
Shows whether the CUPS server is running.
-s
Shows a status summary, including the default destination, a list of classes and their member printers, and a list of printers and
their associated devices. This is equivalent to using the "-d", "-c", and "-v" options.
-t
Shows all status information. This is equivalent to using the "-r", "-d", "-c", "-v", "-a", "-p", and "-o" options.
-u [user(s)]
Shows a list of print jobs queued by the specified users. If no users are specified, lists the jobs queued by the current user.
-v [printer(s)]
Shows the printers and what device they are attached to. If no printers are specified then all printers are listed.
COMPATIBILITY
Unlike the System V printing system, CUPS allows printer names to contain any printable character except SPACE, TAB, "/", and "#". Also,
printer and class names are not case-sensitive.
The "-h", "-E", "-U", and "-W" options are unique to CUPS.
The Solaris "-f", "-P", and "-S" options are silently ignored.
