- PRINT TROUBLE SHOOTING GUIDE
- ****************************
-
-
-
-
- -----------------------------------------------------------------------
- P1 When trying to print to the LPT port in the system, OS/2 returns
- an error stating that the printer is off-line, off, or out of
- paper, or cannot write to LPTx. Also, the printing may have
- worked under DOS, but does not work under OS/2.
- -----------------------------------------------------------------------
-
-
- MICRO CHANNEL / EISA SYSTEMS
-
-
- A1 Verify that the system is operating properly by running diagnostics
- on the system or getting it checked by a service rep.
-
- A2 If there is a NON-IBM parallel adapter in the system, verify that the
- non-IBM adapter is configured for IRQ7 and a different port
- address than any other adapter in the system.
-
- A3 If this is an EISA system with an AT type parallel port adapter
- in the system, make sure that no other adapter uses the same IRQ
- as the printer port.
-
- A4 If there is an (LAN, MIDI, serial, sound) adapter such as a bus
- mouse that uses the same IRQ as the LPT port, reconfigure the
- other adapter to use a different IRQ.
-
-
- AT (ISA) CLASS SYSTEMS
-
-
- A1 See A3 and A4 under micro channel systems, above.
-
- A2 Ensure that there are no other parallel ports in the system trying to
- use IRQ7 and/or the same port address. Change the jumpers or
- switches to configure appropriately leaving LPT1 configured
- as IRQ7.
-
- A3 Insure that LPT1 is configured for IRQ7 and not IRQ5
-
- A4 Bus mice usually use IRQ5 so if printing is failing too, or LPT2
- is recognized, reconfigure the mouse for a different IRQ.
-
- If this problem persists after trying the above, or none of the above
- can be done due to hardware restrictions, the adapter will need to be
- replaced or upgraded. Contact Point of Sale or authorized dealer.
-
-
- ------------------------------------------------------------------------
- P2 Receive printer pop-up that the printer is off-line or it is not
- responding when starting a print job.
- ------------------------------------------------------------------------
-
-
- A1 Please go through checklist in P1 and verify the full hardware
- configuration is correct.
-
- A2 Problems have been found when using certain parallel port
- printer cables that do not meet the parallel port specifications.
- 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.
- Problems with cables longer than six feet in length are more
- evident on higher speed processor systems.
-
- A3 Hold the printer queue, send a job and make sure the job makes it
- to the queue. If not, the printer object is not installed
- properly. Otherwise, it is probably hardware related. Also, you
- can try using the IBMNULL printer driver so that we can insure
- that the printer driver is not at fault.
-
-
- ------------------------------------------------------------------------
- P3 Erratic or slow printing
- ------------------------------------------------------------------------
-
-
- A1 Please go through the checklist in P1 and verify that the full
- hardware configuration is correct.
-
- A2 The parallel port card is probably of older vintage and does not inter-
- rupt correctly. Adapter will need to be replaced unless a system
- board problem is evident, or the adapter card address and
- interrupt level do not match supported pairs. Please refer to
- diagram below.
-
- A3 If there are three LPT ports in a (AT/EISA) system, using AT
- technology cards, it will be normal for one of the parallel ports
- using IRQ7 not to work at the same speed since the AT class
- system does not share interrupts. One of the parallel ports will
- be running off a simulated interrupt that runs off the system
- timer services, which will be the one that is running slower.
- Please refer to diagram below.
-
- A4 Insure that the printer is in the correct emulation mode for use with
- the driver installed. NOTE: Not all printers really emulate 100% so
- we can't guarantee that the driver will work fully with a emulating
- printer.

- IMPORTANT NOTES ON HOW TO CONFIGURE YOUR SYSTEM TO PRINT
- -------------------------------------------------------------------------
- -------------------------------------------------------------------------
-
- On most non-Micro Channel communications (I/O) adapters, the
- configuration is done by either DIP switches or jumper settings.
-
- Most of the systems and adapters purchased should have literature
- that explains the IRQ and port setting for each port that is
- provided by the adapter. If configuration is needed to resolve
- your problem, please refer to this literature or back to the
- point of sale of the system or adapter.
