These PCL fonts can be downloaded to the printer by the
Configuration and Resource Utility.
There is no equivalent of the XES
<ESC>+1fontname<CR><LF> functionality when printing
IBM data streams. Access to fonts must be made by mapping
IBM font calls to the new PCL fonts.
Summary How can I cause the interface to print a separator page between
jobs?
Answer You can print a separator page between jobs in coax by using
the Y100 function which sets the timeout on the coax line as well
as defining an ASCII string which will be sent to the printer
before each job.
Send the following FSL command to the printer:
&&??@@Y100,20,OD200C
&&??<SPACE>
This command causes the coax interface to send the PCL
commands necessary to print a blank page in front of every job.
Be aware that there is nothing in the coax protocol that indicates
to the interface that a new job is being sent. Once the interface
becomes active, it sees everything sent as 1 job. The first
parameter of the Y100 command (20 in the example) is the
timeout on the coax line. By making this value shorter, you will
cut down on the chances of 2 jobs being placed back to back
without a separator page. Care should be taken, however, not
to make the timeout too short, as this may cause jobs to end in
the middle of a page of data if you are running on a slow line, or
if the printer is a long distance from the host. Some
experimentation may be necessary in order to come up with the
optimal timeout value for your particular site.
Summary The printer utilizes multiple ports to receive data (eg. parallel
and coax/twinax), and occasionally hangs.
Answer When a job is received from the coax or twinax interface, a short
PostScript job is sent to the controller to lock the printer into
PCL mode for the duration of the job. The interface then sends
the print job. However, if the Communications Priority Scheme
is set to Sequential, the controller looks for the next job on
another interface (not the coax/twinax interface). If that job is
not PCL or if the job is not terminated with an <Esc> E PCL
command, the printer will remain locked to that port and hang.
