| I
don't get any output on my printer |
|
|
| Q: |
After
calling lpr.css
to
print a file, the file is not printed although the device is
ready. |
| |
|
| A: |
Start
the user interface program and select menu 2.
Printer control.
Now check if the printer status is ready. If the status is 'on
hold', select the printer and activate it. |
| |
|
| Q: |
I
activated the printer, but still nothing happens. |
| |
|
| A: |
Select
menu 3.
Report queue
in the css(U) user
interface program. In the column 'Frm'
check the form name of the report. Now go back to menu 1.
Form change
and check if one of your printers has the required form mounted.
If not, make sure, that the proper paper is in the printer and
tell this fact to CSS.
To do so, select the printer and the form identifier. |

| The
output of my printer looks strange |
|
|
There are several causes that can make your output not to look the way
you expect it to be:
| 1: |
Your
output looks like this:
line 1
line 2
line 3
This
indicates, that your program terminates a line with a linefeed
only, which is common Unix practice. Your printer however
expects a carriage return, linefeed sequence.
You
have two options to fix the problem:
| a) |
Change
your printer configuration to insert a carriage return
before or after each linefeed. |
| |
|
| b) |
Add
the Boolean cr capability to the device definition
in the css.devices configuration file (see
Chapter 'Configuration', Topic Css.Devices(C) in
the CSS Manual). Make sure, that after
changes to the device definitions you have to do a compile
run with the command /etc/csa -d. |
|

|
| 2. |
Parts
of your output is missing or output stops after printing several
pages:
This
indicates, that the handshaking between your system and the
printer is not properly configured. Both partners in a
communication link, the data source (your system) and the data
sink (the printer) must be configured to use the same
handshaking protocol (i.e. Xon/Xoff or DTR) and baud rate. CSS
includes a utility named setmode to permanently configure
serial ports on Unix systems (see
Chapter 'Utilities', Topic setmode(U) in the CSS
Manual).
If
you have installed an additional communication device, such as a
printer box, between your computer system and the printer, the
handshaking of each subpart of the full link must be properly
configured. |

| My
program sends printer control codes, but they vanish |
|
|
To
transparently pass escape codes to a printer, you can define a device
as to operate in binary mode (bm). Alternatively you can spool a single report in binary mode on
normal devices with the -B
option of lpr.css.
It is important to know, that normal CSS
devices use a hypothetical command set from ESC,1 to ESC,127 (two
bytes 0x2701 .. 0x277f). It is up to you to define the translations to
the 'real' escape codes needed by the printer models in use. The
capabilities to do this are e1 .. e127 (see Chapter
'Configuration', Topic Css.Devices(C) in the CSS
Manual). Whenever a program sends an escape code, say ESC,7 and the
target printer has no e7
entry, the two bytes (0x2707) are NOT passed to the device,
since CSS is assuming, that
the target device does not support this feature.

| I
want to preview my report before printing |
|
|
| Q: |
Before
printing my file, I want to verify it in the css(U)
user interface program, i.e. I do not want my file to be printed
immediately. |
| |
|
| A: |
Call
lpr.css
with the -H option. This will keep the report in the queue, until it is
released manually. |

| When
I stop an output, several more pages are still printed |
|
|
When
you stop an output, CSS will stop printing at the end of the
current page. Almost all of today's printer models have buffers to
improve speed. This buffer may hold several dozen pages. Even though
the CSS despooler program has stopped output, the content of
the printer buffer is still printed.
