OS/2 WARP PRINT INFORMATION
===============================================================
This document contains frequently asked questions about printing
from OS/2 Warp.
-----------------------------------------------------------------
1. I installed OS/2 Warp and now I can't print. I could print
under OS/2 2.1 and OS/2 2.11. What do you recommend?
Try editing the CONFIG.SYS statement BASEDEV=PRINT0x.SYS
and add /IRQ.
For the correct syntax, refer to the OS/2 COMMAND REFERENCE under
PRINT01 or PRINT02. Using /IRQ directs the parallel port device
driver to use the interrupt method to print, instead of polling
which is the default in Warp. After adding this change to the
CONFIG.SYS, you must restart the system because the CONFIG.SYS is
read only during system startup.
-----------------------------------------------------------------
2. I installed OS/2 Warp and now I need to install a windows
printer driver. How do I do this?
If you need to add a Windows printer driver after installing this
version of OS/2, you must install the printer driver from the
Windows Control Panel.
To install the Windows driver when creating a printer
object from the OS/2 side:
1. Create a new printer by dragging a printer template
from the Templates folder.
2. Install the OS/2 driver, if not already installed.
3. Press the Create push button.
4. You are be asked if you wish to install an equivalent
WINOS2 printer configuration. Select YES and you are
prompted to insert the proper diskette.
Note: that if there is NOT an equivalent Windows driver, you
are not prompted to install an equivalent driver. Only the
printer drivers that shipped with Windows 3.1 are included in
OS/2 Warp. The drivers are not updated and new printer models
are not included. New Windows printer drivers must be obtained
from either Microsoft or the printer manufacturer.
-----------------------------------------------------------------
3. Does Warp support automatic parallel port printer sharing
boxes?
Contact your hardware vendor to see if the box has been tested
with OS/2 Warp.
You may be able to use this device with OS/2 Warp if you are
using the polling method of printing. DOS uses the polling
method of printing and supports the automatic sharing boxes.
The OS/2 parallel port device driver does not support these
devices in OS/2 2.x releases. You can, however, test the box
with polling on Warp. To make sure polling is being used,
type RMVIEW /IRQ at a command prompt. IRQ7 should NOT be
associated with the parallel port.
-----------------------------------------------------------------
4. What is RMVIEW in OS/2 Warp?
RMVIEW is a utility included in Warp to help resolve IRQ
conflicts. To use RMVIEW:
1. Open an OS/2 Window or Full Screen session.
2. Type RMVIEW and press Enter.
RMVIEW HELP provides the switches available, for example:
- RMVIEW /IO
- RMVIEW /IRQ
If you have /IRQ in the CONFIG.SYS (using the interrupt driven
methodology), RMVIEW /IRQ displays IRQ Level = 7.
If you do not have /IRQ and are using the default (or polling),
there is no reference to IRQ7.
If you have a DMA enabled system and install Warp, the default
is the interrupt driven printing protocol and /IRQ is not in the
CONFIG.SYS.
-----------------------------------------------------------------
5. When do you use the Warp Omni driver?
Support for the Deskjet, Epson and Paintjet drivers has been
merged into one driver called the Omni driver. The Deskjet,
Paintjet and Epson drivers are also provided on the printer
diskettes.
It is preferred that the Omni driver be used when printing to the
Deskjet, Paintjet or Epson printers. The only time the other
drivers should be used is when the system is network attached
and printing to a 2.1 server that is currently using the 2.1
drivers. In this case the Epson, Paintjet and Deskjet drivers
should be installed on the workstation.
If the Deskjet, Paintjet or Epson driver is desired, it can be
installed by selecting "Other OS/2 printer driver" and typing in
the path where the driver is located in the printer INSTALL
dialog box.
-----------------------------------------------------------------
6. Why does the Pulse mini-app indicate my system is being
fully utilized by printing in Warp?
When running the Pulse mini-app in OS/2 Warp and printing at the
same time, Pulse could show the system is nearly 100% utilized.
This is due to polling, the default configuration for the
parallel port when no /IRQ switch is added to the
BASEDEV=PRINT0x.SYS statement in the CONFIG.SYS.
When not many applications are running on the system, polling
occurs continuously during printing. This causes Pulse to
realize the system is being fully utilized by print; however, the
system is functioning normally. As other programs are started,
they start to get time slices on the system. They run normally
due to the system's pre-emptive multitasking ability with task
scheduling. Therefore, multiple applications can function
properly while printing, even though Pulse indicates 100%
utilization.
-----------------------------------------------------------------
7. I am printing to a Lexmark 4029 printer under Warp with the
IBMPCL5 driver. Printing from the command line works, but PM
printing appears corrupt. I did not have a problem under
OS/2 2.1.
The 4029 printer comes with PCL3 support. The IBMPCL5 driver
sends PCL5 data and can only be used with a IBM4029 that has the
additional hardware to upgrade to PCL5 emulation. This hardware
consists of a "daughter card" that plugs into the main circuit
board to give PCL5, like the Postscript option. If you are not
using an application that requires PCL5, try using another
driver.
-----------------------------------------------------------------
8. Can I install a Warp driver on an OS/2 2.11 system?
Due to changes to the printer device drivers and diskette formats
in OS/2 Warp, problems could occur if these drivers are not
correctly installed on any OS/2 2.11 system. Several of the
printer drivers have been upgraded to 32bit and before installing
them, their 16bit counterpart should be deleted.
The diskette format for the drivers on OS/2 Warp has been changed
to 1.88 MB. Before installing these 32-bit drivers on an OS/2
v2.11 system, the drivers have to be copied to a 1.44 MB
diskette and their 16-bit counterparts deleted.
- IBMNULL driver (IBMNULL.DR_)
- LASERJET driver (LASERJET.DR_)
- OMNI driver (OMNI.DR_)
- PLOTTER driver (PLOTTERS.DR_)
- IBMPCL3 driver (IBMPCL3.DR_)
- IBMPCL5 driver (IBMPCL5.DR_)
- IBM42XX driver (IBM42XX.DR_)
- IBM4019 driver (IBM4019.DR_)
On the OS/2 Warp system:
Copy the (driver).DR_ and (driver).EA_ from the Warp diskettes
to a formatted 1.44 MB diskette.
On the target OS/2 2.11 system:
1. Delete any jobs in the queue associated with the Laserjet driver.
2. Open the printer object settings and select the IBMNULL printer
driver as the default (or any other driver that is not in the
family of the driver you want to install, ie..LASERJET) and
close the SETTINGS notebook. Do this for all printer objects
that selected this family printer driver as its default.
3. Perform shutdown and restart the system. Shutdown must be
done to ensure the appropriate driver changes are saved.
4. When the system restarts, open printer object Settings and go
to Printer Driver page and delete all drivers of that family
type.
5. Select Yes when you are prompted: "Do you want to
delete the files associated with this printer driver from
your fixed disk?"
6. Click the right mouse button on the default printer driver and
select Install.
7. The Install New Printer Driver dialog appears. Select
Other OS/2 Printer Driver, using A:\ as the default directory.
8. Insert the 1.44 MB diskette that contains the Warp
(driver).DR_ and (driver).EA_ files in drive A: and select
Refresh. Available drivers are displayed.
9. Select the appropriate printer driver and select the Install
push button.
10. Select the driver as default and close printer object settings.
The object should be available for use.
NOTES:
If the OMNI driver has been installed on an OS/2 2.11 system and
high color support is desired, unpack the LASERJET.DR_ file from
Warp Printer Driver Diskette 1 and copy the PRE32.DLL into the same
directory as the OMNI driver (see the Warp Command Reference for
information on UNPACK).
The 16-bit versions of the Paintjet, Deskjet and Epson drivers are
included on the Warp Printer Driver Diskettes. If these updated
versions must be used, copy the (driver).DR_ and (driver).EA_ files
from the Warp 1.88 MB diskette to a 1.44 MB formatted diskette and
install as normal on the OS/2 2.11 system. When you open the
Printer
Install dialog, select Other OS/2 Printer Driver as described in
question 5.
-----------------------------------------------------------------
9. Is there a user option to switch between polling and the
interrupt driven printing protocol in Warp?
Currently, the polling protocol is the default on all parallel
ports, except for michrochannel parallel ports that have DMA
enabled. If you want to go back to the interrupt driven printing
protocol, you must add /IRQ after the BASEDEV=PRINT0x.sys in the
CONFIG.SYS.
There are currently no plans to provide a user option via the
print object or some other methodology (other than on boot) to
switch between the two printing protocols. There's no API that
the spooler can use to switch between polling and interrupt
driven.
-----------------------------------------------------------------
10. There's no error reported, but the install process appears to
hang when I try to install an OS/2 driver from Warp printer
diskette 3.
There are no OS/2 printer drivers printer driver diskette 3 for
Warp. All drivers are Windows drivers. Select Cancel, insert
the diskette containing the OS/2 driver, and retry the operation.
