- GENERAL OS/2 PRINTING TIPS
- --------------------------
-
-
- DON'T TRY INSTALLING OS/2 2.0 PAINTJET DRIVER ON A 1.3 SYSTEM
- ..
- The OS/2 2.0 PaintJet driver does not work on a 1.3 system.
- This driver (any any other driver) requiring the mirrors.dll
- will not work with 1.3. The mirrors.dll is a 32 bit dll.
- ----------------------------------------------------------------
- DMA PARALLEL PORT ARBITRATION LEVEL
- ..
- When using OS/2 2.0, the DMA parallel prot arbitration level
- should not be disabled. It should be set to SHARED 7.
- When using OS/2 1.3 with CSD 5054 or greater applied, the
- DMA parallel port arbitration level should not be disabled.
- Any level prior to this, should have the arbitration level
- disabled on those systems with a DMA parallel port (PS/2
- models 56, 57, 80-A21, 80-A31, 90, and 95).
- ----------------------------------------------------------------
- PARALLEL PORT PRINTING PROBLEMS
- ..
- If nothing prints on an AT (ISA) bus system, the parallel port
- may be configured incorrectly. This is especially true if the
- parallel port worked correctly under DOS. Up to 3 parallel
- ports can be installed on most systems as long as the port
- address and hardware interrupt levels are set properly. The
- proper combinations under OS/2 are address 3BC and IRQ7, 378
- and IRQ7, and 278 and IRQ5. If these combinations are not
- used, printer error messages or very slow printing will occur.
- ..
- AT bus systems are incapable of sharing hardware interrupt
- levels. This means each adapter in your system must have a
- different hardware interrupt level assigned. Special code
- handles the conflict as described in the paragraph above.
- Many sound cards (Soundblaster) use the same hardware
- interrupt level as the first parallel port and the conflict
- must be resolved if you intend to print. Using IRQ10 with
- Soundblaster is recommended since it does not conflict with
- the parallel ports (IRQ7, IRQ5). IRQ2 cannot be used since
- it drives the slave 8259 Programmable Interrupt Controller.
- ..
- Problems have been found when using certain parallel port
- printer cables that do not meet the parallel port specifica-
- tions. Cables that are longer than six feet in length are
- suspect. Cables that do not contain all 25 wires will not
- work under OS/2. The six foot cable length problem is more
- evident on higher speed processor systems.
- ..
- Some older parallel port adapters fail to generate hardware
- interrupts. These adapters usually work correctly under DOS
- since DOS does not use hardware interrupts to print. OS/2,
- due to its multitasking capability, must use interrupts to
- transfer data out the parallel port. If your adapter fails
- to generate interrupts, it must be replaced in order to
- print under OS/2. If your buffer light illuminates on your
- printer or if your printer prints the first character and
- then an error message is displayed after approximately 45
- seconds, you may be experiencing an interrupt problem.
- -------------------------------------------------------------
- WHAT PRINTERS ARE SUPPORTED?
- ..
- See the file called PRDESC.LST on the first print driver
- diskette with the OS/2 2.0 package. It contains a compre-
- hensive list of all the printer models supported.
- -------------------------------------------------------------
- PRINTER DRIVERS NO LONGER SHIPPED WITH OS/2 2.0
- ..
- OS2TOOLS contains a package called OS2PDRVR. This package
- contains OS/2 printer drivers that were shipped with OS/2
- 1.3, but are no longer shipped with OS/2 2.0. It includes
- IBM3852, IBM5152, IBM5182, IBM52011, and IBM5216. The
- package states that in the future it will contain BETA and
- CSD versions also.
- The printer drivers can also be accessed in Compuserve
- (Library 17).
- -------------------------------------------------------------
- REDIRECTING PRINTER PORT
- ..
- To print to a communications port, you must redirect the
- output:
- .
- 1. Display the pop-up menu for the appropriate printer
- object.
- 2. Select the arrow to the right of OPEN; then select
- SETTINGS.
- 3. Select OUTPUT.
- 4. Display the pop-up menu for the port you want to set up.
- 5. Select the arrow to the right of REDIRECTION.
- 6. Select the port you need. For example, you might
- select COM1 to send your output through a communications
- port.
- or
- .
- 1. Select OS/2 SYSTEM; then select Command Prompts.
- 2. Select OS/2 Window or OS/2 Full Screen.
- .
- SPOOL /D:LPT1 /O:COM1
- PRINT MYFILE.TXT /D:LPT1
- .
- Note: You can redirect output to a COM port; however, you
- cannot redirect output from a COM port to a LPT port.
- The redirection option is only available when two or
- more printer objects are defined.
- ------------------------------------------------------------
- THE FOLLOWING IS FROM OS2TNT DOCUMENT.....
- ..
- General Information
- -------------------
- When installing auxiliary parallel port expansion cards, you
- need to ensure that LPT1 is configured to interrupt level 7
- (IRQ7). Not doing so will cause printing under OS/2 to
- function erratically. Be aware that when using many other
- common adapters such as the SoundBlaster card, they may come
- from the factory configured on IRQ7. Also, many manufacturers
- recommend you configure their cards on IRQ7. Non-microchannel
- machines cannot share interrupts and each card must be on a
- separate IRQ to avoid conflicts. See the reference for your
- adapter cards to configure the IRQs. Additionally, LPT2 cards
- should be configured on IRQ5.

- QUESTIONS, COMMON PROBLEMS AND ANSWERS
- ..
- PROBLEM: Automatic emulation switching does not work
- RESOLUTION: None
- AES does not currently work under OS/2 2.0. Lexmark is working
- on this to be released soon.
- ..
- QUESTION: How does AES for OS/2 interact with 2.0 GA?
- ANSWER: The basic function of AES is to provide a
- convenient method for emulation mode switching on
- the IBM LaserPrinter products. By correlating
- LPT ports with emulation modes on the printer, a
- user can send their job to the correct port and
- set the mode switch properly, and thus not have to
- touch the printer to change emulation modes.
- During AES install, the option is given to the user
- if they want to install extra LPT ports (as the
- LPTX.SYS Device Driver). This driver is the same
- identical driver that is used by the Lexmark
- External Network Adapter, IBM 4033. It essentially
- allows for character monitors to be installed on
- LPT ports > 3. Then the character monitor does
- what it needs to, and re-directs that data to the
- physical port where the printer is connected. Or
- in the case of the IBM 4033, the data is
- re-directed (by the character monitor) to the
- Token Ring or Ethernet PS/2 card
- ..
- PROBLEM: Printing problems with parallel ports - nothing
- prints.
- RESOLUTION: Ensure that LPT1 is configured to use IRQ7 and
- LPT2 is configured as IRQ5. Check the printer
- cable to ensure that the cable runs all 25 lines,
- not all cables wire the necessary lines. If the
- problem persists and you are convinced it is not
- an interrupt problem, cable problem or just the
- wrong driver, the problem may be with your I/O
- card. Some older I/O cards do not work in OS/2.
- ..
- TIPS AND TECHNIQUES
- -------------------
- If you send a print job to a printer that is powered off, you
- may experience a corrupted job when responding to the RETRY
- dialog after powering on the printer. You should cancel the
- job and resubmit it after turning on the printer.
