Parallel Print Data Recorder

Keep printing while data is recorded onto popular memory cards.

Model PDX-R attaches to a legacy system parallel data cable, and is able to record the raw print data with or without
a printer being connected.  The memory card is inexpensive and popular, and the data can easily be transferred to
a PC folder using a PC media card reader. 

There are no front panel controls or settings, "just plug in", and begin recording. You may record for days or weeks
before reaching its storage capacity of 2 Gigabytes.  That capacity can store approximately 20 million lines of text data.

Use to:
Archive print data for quality assurance or record keeping.
(Example: FDA 21 CFR Part 11 Compliance).
Eliminate redundant printers, eg. alarm printers.
Capture databases from retiring legacy systems.
Eliminate manual transcribing of printout to other systems.

Printers may include:
Desktop Dot Matrix (eg. Okidata, Fujitsu, Epson, Roland, Panasonic)
High Speed Lineprinters (eg. 1,000 lines/minute)
InkJet printers (non GDI/Winprint style)
Laser printers (non GDI/Winprint style)
Thermal Barcode Label printers (eg. Datamax, Zebra)
POS Printers (eg. Epson)
Alarm Printers

1. You can record a 1,000 byte report line of data every 5 minutes for 6,944 days. 2. You can record enough data to keep a common 200 char/second dotmatrix printer printing generic text data constantly for 112 days.
The print data stream from the users parallel cable is recorded without any formatting applied.  The memory card
is recognized as a disk drive on the PC, example "F" or "G" drive. The recording file name is always: RECORD.TXT This file may contain any 8 bit data, such as photos, barcodes, rich text, fonts, or any data that has a byte value range of 00 Hex to FF Hex. If the data is dumped from the PC folder file to a similar printer, then an exact reprint may be obtained.

Only RECORD.TXT file created by the Model PDX-R is allowed on the memory card. The recorder will append print data to the file if the card is removed, then returned to the recorder. In the evnet of power outages, the unit is meant to recover
automatically, and begin recording on the card where it left off. The user erases the memory card by deleting the RECORD.TXT file on a PC. The Model PDX-R automatically creates a new empty RECORD.TXT file. Two LED's on the front panel blink alternately to show the user at a distance that the unit is functioning. DISPLAYING THE RECORDED DATA
Many printers print plain text data. In that case the recorded data should display satisfactorly in a wordprocessor such as MS Notepad or Word. Such data may also open in spreadsheets if the print is columnar type, eg. alarm printer data, reports from scientific instruments including scales and balances. If the printing system is "non-text" such as printing rich text or graphics using a printer emulation , eg. Epson Escape Commands or PCL Commands, then the user can consider applying viewing software that is available from many suppliers, eg. use PCL viewing software when the print stream is using PCL emulation. Another example is PCL to .PDF software converters. No software is provided by Photologic Ltd. Some user sites are prepared to develop their own software that will open large .TXT files and parse the data, and display it for specific use.
