Phaser 220 Drivers and Utilities
These utility Þles use PostScript Level 2 operators that are not supported
under PostScript Level 1. Each Þle contains code that checks whether
PostScript Level 2 is supported by the printer before making a change to
printer performance. It is recommended that you only use these Þles with
Level 2 printers. If you send one of these Þles to a Level 1 printer, it won't
make the requested change and it won't generate an error.
All PostScript utility Þles, except RESET.PS, must end with a Control-D
character when sent from a workstation over a serial or parallel interface. In
the Þle descriptions, Control-D is denoted as CTRL-D. For more
information about PostScript programming, refer to the PostScript Language
Reference Manual, second edition, Adobe Systems Incorporated.
If your workstation is connected to an Ethernet network such as NetWare or
TCP/IP, you should delete the Control-D characters from each utility Þle
that you plan to use.
Removing Control-D characters from utility files
1. Locate the delctrld UNIX shell script in the PHSR220 directory on
the Printer Utilities diskette for PC/DOS. You must copy this Þle
to your workstation before you can use it. (Or, obtain this shell
script through one of the methods described in the topic
ÒObtaining the utility Þles,Ó in this chapter.)
2. To remove all Control-D characters from a Þle, type the following
command:
delctrld Þlename1.ps Þlename2.ps
where Þlename1.ps is the utility Þle you want to remove Control-D
characters from, and Þlename2.ps is the revised Þle with a new
name. (Both Þlename1.ps and Þlename2.ps can have the same name,
but the original Þle will be overwritten by the revision.)
3. Send the utility Þle to the printer in the usual manner.
