Many different OEM organizations have been integrating Printrex products into combined  
hardware and software systems; some for nearly 20 years. These complete-solution products  
may be assembled in closed physical packaging or racks, or may consist of pre-configured  
computer hardware that is deployed like any other office equipment. Software may be  
command-line or graphically operated, and might be installed with a Unix-type or Microsoft  
operating system. Interconnection interfaces include various types of parallel or serial  
ports, USB and/or Ethernet.  
OEM  
Configurations  
While Printrex has experience in supporting the development of a variety of these OEM  
systems, it is impossible for us to maintain the information and knowledge necessary to  
provide detailed support in the operation of these systems. Persons having questions  
regarding use of a specific product are best advised to consult the documentation or support  
services provided by the OEM.  
For clients directly receiving Printrex products to install as end users into existing or new  
systems, we wish to make the installation process as trouble-free as possible. Several  
documents are available for reference which are intended to describe the most common  
installation scenarios (see the Additional Documentation section of this guide).  
First, be sure to use a high-quality cable. The cable should be marked “IEEE-1284” to  
indicate compliance with this communications standard. Inexpensive cables are electrically  
inferior and can result in unnecessary communications errors.  
Connecting the  
Parallel Interface  
Connect the 25-pin connector end of the cable to the parallel port of the computer. Use the  
screw locks to secure the cable, but do not tighten excessively.  
Make sure the printer power is off, then, plug the Centronics 36-pin connector end of the  
cable into the printer and engage the spring clips to lock the connector.  
Avoid making any other connections between computer and printer, whether to add extension  
cables or to install daisy-chain disk drives or scanners. Integrity of communications is  
greatly degraded when these items are in the signal path.  
For other installation and connection options, please refer to the Printrex System  
Administrators Guide.  
First turn Power Switch to the off position (the off position is shown by the international  
symbol “O”). Connect the IEC female end of the cord to the power connector on the rear of  
the printer chassis. Plug the male connector into a properly grounded three- pin AC main  
power outlet.  
Connecting the  
Power Cord  
Do not use a “cheater” connector in order to use an inexpensive two-wire outlet or extension  
cord. This defeats the grounding protection of the product and may introduce a serious  
electrocution hazard in wet environments.

System Setup  
2-2  
The majority of Printrex customers use our printers with computing equipment that functions  
with the support of an operating system. Microsoft Windows XP and Windows 2000 are  
the most prevalent systems in current use. In order to provide the best quality of printed  
output and most convenient user interface, Printrex continually reviews and updates drivers  
for these platforms.  
Operating System  
Setup  
The ‘consumer’ operating systems ( Windows 95, 98, and ME ) are in the twilight of support  
by Microsoft and are therefore supported at a lower priority by Printrex as well. Specific  
issues regarding current drivers for these platforms may be referred to Printrex technical  
support for correction; custom feature additions will be addressed on a per request basis.  
The paragraphs below apply to users installing printers by connecting directly to the computer  
in use. For connecting to a network, see the following section on Network Setup.  
WindowsTM 2000/XP  
Because drivers for these platforms are subject to periodic updates, visit the Printrex website  
compressed file onto a floppy disk and open the Printers folder ( Start – Settings – Printers).  
Start the Add Printer wizard and follow the instructions, selecting Have Disk when prompted  
for ‘Manufacturers’ and ‘Printers’.  
After completing the wizard, right-click on the new printer icon in the Printers folder, and  
select ‘Printing Preferences’. Click the Advanced... button to display the Advanced Options  
dialog. This determines the “default” settings of the printer. Most users will wish to change  
the Paper Size from ‘Letter’ to the actual form loaded in the printer, as well as the Media  
Selection and Form Marker Type. Other settings may need adjustment as well, depending  
on application.  
For further information on installation, see publication 1028-0061, Printrex Driver Installation  
Guide.  
After installation, publication 1028-0062, Printrex Windows Driver User Guide may be  
used as a reference in applying the driver settings needed for a particular printing task.  
Many different types of applications can be accommodated by the drivers, using a variety  
of media. While the default control values are a good starting point for most print jobs,  
many users will wish to fine-tune driver settings to obtain the best quality possible.  
WindowsTM 95/98/ME  
First, check the Printrex website for updated driver versions ( www.printrex.com/drivers.htm).  
After extracting the compressed driver files to a floppy disk, go to the Start – Settings –  
Printers folder, and double-click Add Printer. Proceed with installation, and click the Have  
Disk button when the ‘Manufacturer’ - ‘Model’ dialog is displayed. When the wizard  
finishes, right-click on the printer icon and select ‘Properties’. Make adjustments as needed,  
for paper size, media type, and other features. For further information on installation, see  
publication 1028-0063, Printrex System Administrators Guide.

UNIX and Other Operating  
Systems  
At this time, Printrex does not distribute filter files for UNIX (and UNIX-type) platforms.  
Users of applications designed for use on these systems are advised to contact the application  
vendor for assistance with setup.  
Many permutations of network connections and configurations exist. It is well worth taking  
some time to design the installation with consideration to future expansion and updates.  
Network Setup  
When connecting the printer within a mixed environment, there are additional choices  
available and decisions to be made. Hardware print server boxes provide multi-protocol  
support for numerous platform configurations and communications standards.  
Refer to publication 1028-0063, Printrex System Administrators Guide for further information.

To perform self test, press and hold the PAPER ADVANCE button while turning on power.  
The PAPER ADVANCE button may be released after self test has started. In self test, the  
ERROR indicator lights and a printout of model, interface type, firmware version and other  
various test patterns is started. The test printout will stop after the last test pattern is printed  
and the printer will exit self test and return to normal operating mode.  
Running Self Test  
There are times when it is useful to have the test pattern repeated. If the PAPER ADVANCE  
button is held while the first self test pattern is finishing, the printer will enter a repeating  
self test mode where the entire self test pattern is repeated until the unit is powered off.

Operation  
3-4  
After loading paper, or any time you wish to advance paper, press the Paper Advance button  
on the front panel. The printer will feed paper as long as the button is pressed, but will stop  
when either of two conditions is met:  
Advancing Paper  
If the paper has form markers printed on the back surface, the printer will stop  
when a marker is detected.  
The logical page length has passed without a form marker being seen. The power-  
up default page length is 16.7 inches. This length may be changed by sending the  
printer control codes in software.  
Releasing the button and pressing again repeats the cycle of feeding and stopping.  
When print jobs are sent to the printer continuously, there is no mechanical duty cycle  
limitation; some users report 10 hours a day of nonstop printing as normal usage. However,  
if the print data contains an unusually high proportion of black areas, the printer may go  
into an over-temperature condition. This may also occur when printing less dense print  
jobs if the ambient temperature is very high. Refer to the following section on Errors and  
Error Handling for information on the front-panel indication of temperature errors. Recovery  
from temperature errors is automatic, and needs no user action to resume printing.  
Printing  
If paper has been loaded askew, or has been torn off forcefully, or is damp, the paper may  
feed abnormally and wrap around the platen roller. These occurrences are extremely rare,  
but it is important to know the following method of clearing the jam:  
Clearing a  
Paper Jam  
Turn off power to the printer.  
Open the printer door, and remove the paper holder and roller.  
Tear off the incoming paper (either from the roll, or fanfold supply).  
Pull on the free end of paper with one hand, while turning the platen roller with  
the other hand, to unroll paper from the platen.  
Do not use a razor, knife or sharp object of any kind to cut the paper off of the  
platen roller. Nicking or cutting the roller surface will result in worsening damage  
to the platen with continued use of the printer.  
Be very careful not to damage the print head that is exposed on the underside of  
the door. This should not be an issue if only bare hands are used to free the paper.  
The Front Panel controls are intentionally minimal. This ensures that one users print jobs in  
a network environment are not ruined by other users manually making unannounced changes  
to printer settings. The Printrex Windows drivers send control codes to the printer for each  
print job, so it is important to check driver settings before printing. Note that some  
geotechnical applications bypass the Windows drivers, and provide a limited subset of  
printer controls. Check with your applications documentation to determine if this is the  
case. If so, settings made in the Windows driver will not affect printing from these  
applications.  
Additional Controls

The Error Indicator on the Front Panel indicates an error condition of the printer.This indication  
is in the form of a two digit error code expressed as a series of long flashes (for the tens digit)  
then short flashes (for the ones digit). The tens digit flash is twice as long as the ones digit  
flash. Example: One long flash followed by two short flashes indicates an error code of 12  
(Door Open).

This section lists a few common questions that are received by Printrex support staff and the  
answers most likely to fix the problem. For further information, see the Printrex System  
Administrators Guide.  
Troubleshooting  
1. The printer seems to be working but nothing is printed.  
The thermal paper has one side that has a thermal sensitive coating while the other side is  
not coated. Be sure the thermally coated side is facing upward (as the paper is exiting the  
printer).  
2. My printer is too slow! What’s wrong?  
(Windows XP/2000/NT4)  
These operating systems do not support high speed data transfer using the default (Microsoft)  
parallel port driver. Printrex recommends using a USB to Parallel converter cable when  
connecting the printer directly to PCs using these operating systems.  
(Windows 95/98/ME)  
Check the parallel port settings in the BIOS and be sure its set to ECP mode.  
3. I’m using fanfold paper with form markers, but the printer stops in the wrong place.  
What driver settings should I use?  
Be sure to set the Paper Size to the actual size of the paper (8.75 x 6.25), and enable End-of-  
Job Form Feed. Also, see that the Form Marker setting (in Windows XP/2000 driver) matches  
the actual printed location of the marker. Check that the paper is loaded correctly: looking  
at the front of the printer, the marker should be on the right side, on the bottom of the paper.

4. I’m trying to print TIFF files, but the printed output is clipped off. How do I print the  
whole log?  
Troubleshooting  
(Continued)  
This question has come from the geotechnical community frequently over the last several  
years. Commonly, users view TIFF logs in Windows Imaging, the free viewer provided in  
the Programs- Accessories folder. Unfortunately, this is a single-page application: it is  
designed for simple photograph- size viewing and printing. Further, the Windows printing  
subsystem (prior to Windows 2000) limited printer pages to 32,766 raster lines (approximately  
163 inches long for the Printrex printers), so the longest log that could be printed from  
Imaging was just 13 feet long. In Windows XP, the Imaging applet was replaced by a new  
Paint applet that does print using multiple printer pages. In this case, set the printer page  
size to the papers page size (8.75 x 6.25 half page), and Paint will generate as many printer  
pages as needed to print the log.  
In most of the larger geotechnical organizations, proprietary viewers have been written for  
internal use by authorized staff and customers. Remarkably, there are very few options for  
other users of TIFF log files who are not using Windows XP, or who find the XP Paint  
application too primitive.  
Printrex welcomes comments regarding requirements and features for log viewing tools,  
for possible development of a viewer application for our customers.  
5. Every time I start my program, I have to change printer settings. How do I change the  
default driver settings?  
In Windows 95/98/ME, go to the Start – Settings – Printers folder. Right-click on the printer  
icon, and select ‘Properties’. In Windows NT4, right-click on the printer, and select  
‘Document Defaults’... not ‘Properties’. In Windows XP/2000, right-click on the printer,  
and select ‘Printing Preferences’. (If you select ‘Properties’, go to the ‘General’ tab, and  
click the ‘Printing Preferences’ button.  
In Windows NT4/2000/XP, changes to the printer settings done from within an application  
are generally not saved unless some unusual program coding is done.  
6. Self test prints out OK but when I print from the computer I get garbage.  
Common problems for this symptom are the parallel cable or the printer driver that is being  
used. Be sure the parallel cable is appropriately connected (see section Connecting the  
Parallel Cable). Also, be sure the printer driver is for the specific model printer that is being  
used.  
7. Some times the fan-fold paper skews to one side or the other. How do I correct this?  
The Printrex printers are designed to work with a wide  
variety of media. A paper skewing problem is  
normally corrected by realigning the paper. This  
is done by opening the door, straightening the  
paper and closing the door. We have found  
however, that under some conditions (generally with  
very thin paper) the problem may persist. If this is the case, we suggest threading the paper  
over a full internal roll of paper (as shown) to remedy the situation.

Care and Cleaning  
4-1  
There is no regular cleaning required for proper operation of the printer, however the  
printer surfaces are designed and manufactured to permit cleaning with the following  
cleaning agents:  
General Cleaning  
Isopropyl alcohol  
Ammonia  
Chlorine bleach (1:10 concentration with water)  
Hexachlorophene (PhisoHex)  
Glutaraldehyde (Cidex)  
It is recommended that a soft cloth dampened with the cleaning agent be used to clean  
the surfaces of the printer. Do NOT submerse or allow spills onto or in the product.  
The thermal head incorporates a protective glaze coating and is generally resistant to  
harsh environments, however the following precautions should be taken regarding the  
thermal head surface:  
Protecting the  
Thermal Head  
Do not allow the thermal head to come in contact with sharp or hard objects.  
Do not allow thermal paper debris to accumulate on the thermal head.  
Do not allow condensation to accumulate on the thermal head.  
Use only Printrex approved thermal paper  
Do not expose the thermal head to abrasive cleansers.  
Paper dust or other foreign material may occasionally accumulate on the thermal print  
head. This will be indicated by light print or no print in a narrow band down the length of  
the paper. In order to eliminate the thermal paper debris buildup, it is recommended to  
use a soft cloth moistened with one of the following cleaning agents:  
Cleaning The  
Thermal Head  
Isopropyl alcohol  
Ethanol  
A light wiping along the length of the print head is adequate. Allow the print head to dry  
before resuming printing. It can be wiped dry with a soft, clean cloth. Do NOT submerse  
or allow spills onto the thermal head.  
Paper dust or other foreign material may occasionally accumulate on the form sensor.This  
will be indicated by missing the top of form position (some time after it has been correctly  
stopping at the top of form). The form sensor can be cleaned with an aerosol air spray or  
soft bristled brush. It is located just under the form sensor window.  
Cleaning The  
Form Sensor  
With the paper door closed, the thermal head applies a considerable pressure on the  
platen (approximately 8 kg). If the printer is stored for long periods of time with the paper  
door closed (especially in cold temperatures), it is possible that a slight flat area is induced  
in the platen. It is recommended the paper door be kept in an unlatched condition for  
extended periods of storage. Note:The condition of a flat spot on the platen is not permanent  
and the platen will return to its normal roundness after 10 or so minutes of resumed  
operation.  
Long Term  
Storage
