echo “\033)0B\c”
The command used to set the pitch to 12 cpi is:
echo “\033(s12H\033)s12H\c”
To make changes to character sets not supported by the script, you will have to
add changes to the interface script. In this case, the user chooses the pitch with
the lp -o pitch=condensed or similar command.
In PowerPC virtual printers, the printer is initialized by the ci attribute sequences.
These are set from SMIT, the Web-based System Manager, or lsvirprt. Users
can select the print style and pitch with the qprt -s style -p pitch flags. To
support font sizes or styles not supported by the virtual printer requires special
customization. For PCL printers, this is usually done with the mU attribute.
What is the LANG variable set to?
For the PowerPC print subsystem using virtual printers, the installation LANG
variable will set the input translation table for the particular virtual printer. This will
show up in the _X attribute. For example:
# lsvirprt -q asc -d lp0 -a X
Name Description Value
_X CODE PAGE of print file ISO8859-1
The default codepage for the US is ISO8859-1. One of the problems that people
experience is that files with box characters do not print the boxes correctly when
this codepage is used. To print a simple ASCII text file that contains line drawing
characters, specify the IBM850 codepage by changing the X attribute, or using
the following command:
$ qprt -XIBM850 -Ptext /tmp/testfile
12.1.8 The print job requests the wrong paper size
For PCL or other ASCII printers, make sure the default paper size is set right in
the virtual printer or interface script. Next, make sure the command for the paper
size is not embedded in the file. For PostScript files, the paper size is often
defined inside the print file itself, and there is little you can do in the virtual printer
or interface script to change it. You should go back to the application that creates
the file.
12.1.9 Network print jobs fail to print
When printing to network print servers and network printers, the goal of
troubleshooting is to isolate the problem to the print client or server and then to
do local problem determination.
