PS Protocol
Option
5-31 Additional Technical Information
Advantages
The main advantage of using the Binary and Binary Fixed PS protocol
modes when sending binary data is that these modes compress the
data stream allowing your documents to be smaller so you can send
smaller jobs to the printer. For example, some device drivers can for-
mat bit map images as binary data instead of as ASCII hex data.
Implementation
To implement PS protocol for sending binary data on your system you
need a device driver available with some applications or operating
systems, or you can alternatively use a program to read the data and
write out the quoted characters. Contact QMS for any available infor-
mation on device drivers or binary filter programs.
Qbinary (Quoted Binary) Fixed—Enables
binary communications protocol. Print
jobs cannot alter this value through
PostScript operators. Data in the
printable ASCII range also prints. Use
the special quoting mechanism for the
special characters and ^D (EOF).

Ring
Default Normal
Notes A data stream sent through the serial or parallel interface
using Binary is treated the same as a data stream sent
through an optional network interface using QBinary.
However, a data stream sent through an optional network
interface using QBinary is not treated the same as a data
stream sent through the same interface using Binary.
