-
- This Software is supplied `as is'. It is
- designed to enable full duplex printing of a wide
- range of DTP documents on a Hewlett Packard (or
- equivalent with PCL emulation) Laserjet printer
- with a full DUPLEX option.
-
-
- An IMPRESSION PUBLISHER version of this manual
- is available to all registered users.

- Introduction
-
- In order to enable printing on both sides of the paper many
- current systems require that you turn over the output stack
- of paper after printing the first side and then re-insert it
- into the printer input tray to print the second side. This
- can be very time-consuming and it can prove difficult to
- achieve an easy flow of paper on the second side.
-
- The first problem is the need to `square off' the stack of
- paper in order to place it back in the imput tray. Due to
- electrostatic effects and slightly uneven stacking it can be
- quite difficult to replace it in the tray so that it `feeds'
- cleanly and evenly for the second side.
-
- There can also be problems with paper `curl' which may
- affect the pick up mechanism causing missfeeds and even
- paper jams.
-
- High quality paper helps but this can prove expensive.
-
- Many of these problems disappear if you can use a printer
- with a duplex option ie. one which is able to turn the paper
- over automatically and print the second side. Most laser
- printers can be bought with this option and some can be
- updated to full duplex.
-
- There are however at least three remaining problems a) Many
- LaserJet Printer Drivers do not have a duplex option b) The
- printing options on DTP packages may print pages in the
- wrong sequence for the duplex printing. c) The margins set
- by many printers on front and back printing passes are wrong
- for duplex.
-
- LjDuplex can help solve these problems by modifying the
- output of the printer driver a) By inserting the necessary
- duplex commands into the print string b) By re-ordering the
- pages as required and c) Resetting the `Logical Page' so as
- to make the front and back margins equal. For convenience it
- can also modify the number of copies printed. You can print
- a test copy and then send hundreds of copies to the printer.
-
- Requirements
-
- A hard disk is essential. The LaserJet printer used must
- have a `duplex'' option and enough memory to hold all the
- text and graphics on both sides of the paper. It should be
- connected to the parallel port of your Archimedes.
-
- Status
-
- This software has been tested using Impression Publisher on
- a RISC PC using the standard Acorn Hewlett Packard printer
- drivers. It may also work for other Archimedes machines and
- for other DTP programs and drivers. If you have problems
- please send a copy of your print file (see later) with
- details of your machine configuration to Mijas Software and
- we will attempt to resolve it. If is NOT intended for use
- with Laser Direct type printers or other printer types which
- do no use the Hewlett Packard PCL printer language.
-
- Installation
-
- Copy the software provided to a convenient position on your
- hard disk. Identify a disk location for the output file
- which will be generated by your printer drivers. NOTE this
- can be many megabytes! Configure your printer driver to
- output to file (see later if you have not done this before).

-
- Updates
-
- Mijas Software would be pleased to have the opportunity to
- look at any problems/suggestion which you may have in using
- this software. Please write and send a disk example of your
- printer output file.
-
- Booklet Printing (A5 on A4 landscape)
-
- Construct your booklet in A5 page format as usual ensuring
- that you have a multiple of 4 A5 pages. Print as for 1 copy
- in booklet format and allow both sides to be printed to a
- single file. Double click on the !LJduplex icon and `drag'
- your printer output file onto the ljduplex iconbar icon. The
- first time this is done we suggest that you click with
- `MENU' on the LjDuplex icon bar icon go to the `save
- choices' option and click on it. This will save your
- configuration, Next choose the number of copies to be
- printed, leaving the other options at the default settings
- initially. When ready click on `PRINT'. Once set up, this
- process can be repeated as often as required. We suggest
- that you print one check copy and then any longer run when
- this has been proof read.
-
- Left/Top offset
-
- The is an option on the dialog box to set the left margin
- of the printout. Many laser printers have a larger TOP
- margin (in booklet or landscape this is the left) than the
- BOTTOM or right margin. Since the paper is turned over
- between passes TOP and BOTTOM are changed over. This can
- make it very difficult to print booklet pages so that the
- front and back margins `match'. Often attempts to do this
- result in `clipping' of one side or a very reduced matching
- print area. The cure is to reset the position of the LOGICAL
- PAGE of the printer so that the top and bottom margins are
- the same. This is done by putting a (usually) positive value
- in the left/top offset box. The value is in picas (1/720
- inch) at the default choice of 280 is about right for our
- Laserjet III SI duplex printer.
-
- Collated
-
- When multiple copies are printed the default is to print
- all the copies of the first sheet and then all the copies of
- subsequent sheets. If the collated option is set LjDuplex
- will print successive full copies which do not require
- subsequent collation.
-
- Alternate Output Trays
-
- When the collated option is not in use it can be convenient
- to send alternated output sheets to alternate output trays
- on the printer. This enables long print runs to be carried
- out with minimum supervision. Non-Booklet Printing (A4
- Portrait) LjDuplex can be used for other duplex work. e.g.
- Duplex A4 in portrait mode. This will require LjDuplex to
- be set for long edge binding by clearing the short edge bind
- flag. In this case the left/Top offset becomes a top margin
- adjustment. A value of 280 is again just about right for our
- IISi laser printer.
-
- A5 Pamphlet printing
-
- If you wish to print two duplex A5 pamphlets on a single A4
- sheet for subsequent cutting to A5, proceed as for normal
- printing but create only the two pages required. Load the
- printout file into edit and drag a second copy into the edit
- window and save. This will then print as required.
-
- Printing to file
-
- Double click on !printers to bring the LsJet icon onto the
- icon bar. Click on the icon with `Menu' and then on `Printer
- Control. Click on the LaserJet entry with `Menu' and then on
- `Connection'. You can then click on `File'. Click on the
- `File' radio button and then on the `Menu' option on the
- right hand side of the `File' line and drag the `PRINTOUT'
- file to a suitable place on your hard disk. (This is the
- file you will later `drag' onto the LJduplex icon.) Finally
- click on `OK' to set printing to file for this session only.
- (ie until you click on the `Parallel' option or re-boot). If
- you also click on `save-choices' on the Laserjet Icon on the
- Icon bar the printer file will be `remembered' by the system
- and you will be able to switch from printing direct to the
- printer or printing to file by just clicking of the radio
- button on the `printer connections' dialogue box. To change
- your `standard' configuration back to direct printing click
- on the `parallel' radio icon and then again on `save
- choices' on the icon bar menu.

- Mijas Software
-
- Mijas Software was set up to bring specialist applications
- already available elsewhere, to the Archimedes range of
- machines. This current duplex program was generated in
- response to an internal requirement for generating
- manuals/magazines etc. in A5 format using the Impression
- program. Other products include the ArcSimp analogue/digital
- simulation program which is aimed at educational, hobby and
- industrial applications. Mijas Software are always
- interested in users comments/requirements. Please contact us
- if you have any suggestions (or brickbats!).
