WLPR is an implementation of a BSD Unix LPR client. This allows a PC
runnig Windows 95, Window 3.1 or Windows For Workgroups to send files
over TCP/IP to a printer for printing. WLPR does no formating, a file
must be written containing the correct instructions for the printer.
This is typically done by selecting the correct printer type and the
"print to file" option in the application that created the document.
Once a file is created it can be sent to the printer either by dragging
and dropping it on the WLPR window or icon or using the Windows 95
sendto feature.
In Windows 95, files cannot be dropped directly on the task bar.
Instead if a file is dragged over an icon on the task bar and held there
for a second or two the application window represented by the icon
is expanded. The window can be anywhere on the screen and you must now
move the mouse to the windows location. However, WLPR automatically
moves the mouse when the its window is restored so all you need to do
is drop the files.
WLPR makes use of an INI file in the WINDOWS directory. Currently the
WLPR.INI file looks something like this:
[DEFAULT]
PRINTER_HOST_NAME="pinetop"
PRINTER_NAME="JetDirect1"
USER_NAME="Noah_Davids"
DEBUG=0
DELAY=1
[Version]
Version=1.2 - 1/1/96
Copyright=Copyright Noah Davids 1995
The DEFAULT section contains the information used to control the print
request.
PRINTER_HOST_NAME is the name of the host running the LP
daemon. It may be another conputer or a network aware printer. Currently,
it must be a name that will be resolved by looking it up in a host
table or with a query to a domain name server. It cannot be an IP address.
PRINTER_NAME is the name of the printer. Network aware printers may or
may not care what name you provide, it will depend on how they are
configured - HOWEVER, a name must be provided for WLPR to use.
USER_NAME is the name that you want to use on the header sheet that
is printed before your actual file. How this is printed is dependent
on how the printer host and printer are configured.
DEBUG should typically be 0. If it is sent to 1 a great deal of debugging
information will be displayed in message boxes as the program executes. If
its set to 2 you will also get a dialog box containing all the characters
that are sent to the printer.
DELAY is the number of seconds that the "Done Printing" message is
displayed.
Percent Complete dialog box:
WLPR displays a dialog box that contains the number of bytes
in the file, the number of bytes read and the number of bytes sent to
the printer host. On a busy network, or with a slow connection to the
printer host its possible for these byte counts to pause for a few seconds.
This is not typically a cause for concern. Once the contents of the file
is sent to the printer host a control file is sent. This file contains
information like your name. The dialog box will display a message indicating
that the control file is being sent and the bytes sent to the printer will
incremented as the control file is sent. Once the control file is sent the
"Done Printing" message is display for DELAY seconds. Short files can be sent
so fast that its easy to miss this dialog. The "Done Printing" message is used
to make sure that the user has time to see that the file has been printed.
Request dialog box:
Wlpr is being released as shareware. as such its expected that if you routinely
use it you will register it. The dialog box is a reminder of that.
To register send $25.00 to:
Noah Davids
6115 East Surrey Ave.
Scottsdale, AZ 85254
Please include the Wlpr version and where you got it from.
Questions can be sent to the above address or via email to:

Error handling:
There are many reasons for either TCP or the printer host to return an
error. If any error is returned the print request is aborted. Errors
from the WinSocket subsytem are reported numerically. The following
table can be used to interpret them. Errors returned from the printer
host are more cryptic and typically are just a "message not acknowledged"
indication. If you get one of these errors try again in a few seconds.
If the error persists talk to someone who is in change of the printer
and the printer host to make that it is functioning correctly.
