- Welcome!
-
- This is Project Printer, 1987, a task we have amusingly subtitled "The Search for Spec." Those of you who have
- participated in the printer blockbuster project in previous years will notice small differences between those tests of
- the past and this new undertaking. Those of you who are new to the project will reach a definite conclusion: there's
- quite a bit of work to do.
-
- For your edification, enjoyment, and to give you something to strangle in times of fruitless endeavor, we've
- prepared this document. We urge you to read it first, before you start any of the tests. It will save you quite a bit
- of frustration and no small amount of time.

- The Tests
-
- You'll be testing a variety of printers, dot matrix, letter quality (a.k.a. "Daisey Wheel") and laser printers.
- The tests we've compiled are meant to extract the ultimate performance comparisons across the varied possibilities by
- highlighting as many compatible features as possible.
-
- You must fill out ALL information on the front page of the script. It's not an option, and whatever isn't
- available from the manual should be available from the printer manufacturerer or vendor. By the way, read the printer's
- manual. That's not a suggestion.
-
- Check the PRBENCH subdirectory on the computer you're using. You should have the following files:
- If you see more than these, that's fine. But you should have all of these files.
-
- Start the program by typing PRBENCH at the DOS prompt. You can do this either from the root directory (which
- contains a BATCH file called PRBENCH.BAT) or from the PRBENCH subdirectory. The questions will appear either
- sequentially or in menu format.
-
- The first two questions are simple. You'll need to enter the proper name of the printer you're testing (make sure
- you use the correct model designation as there may well be more than one printer from the same source). Follow that
- with it's tag number. You'll be asked if the data you've entered is correct or not. Respond accordingly.
-
- Now for the tough part. This section of the program asks for 10 pair of printer control codes that might possibly
- be used to enhance the printing of the printer you're testing. These codes should be clearly delineated in the
- printer's manual. (Note: the list of control codes listed in the back of the IBM ProPrinter manual does not show an
- OVERSTRIKE code, yet the codes for this feature are mentioned within the body of the manual. That's why it's important
- that you actually read the manual.) You can enter each control code directly from the keyboard. If the code you need
- falls below ASCII value 32, hold down the ALT key and type the numbers from the keypad, NOT from the top row of numbers
- at the main keyboard section . When you release the ALT key, that code will appear. (E.g. DC2 is ASCII 18, so hold
- down ALT and sequentially press 1 and 8; then release ALT.)
-
- Don't be alarmed if not all of these printer features apply to your printer. The ones we've chosen represent the
- optimum number. If you come across a feature that's not supported (like Italic, for example), press the END key through
- both turn-on and turn-off entry routines. If you hit the wrong key by mistake, just press DEL. It deletes the last

- entry. And, of course, you can bypass the entire procedure at the start or at any time by pressing the HOME key. (IF
- THE PRINTER YOU'RE TESTING IS A POSTSCRIPT PRINTER, DEFINITELY BYPASS THIS SECTION OF THE TEST.)
-
- Remember, Bold printing is, in theory at least, a horizontally mis-aligned overprint of characters while emphasized
- (also called double strike), is a re-strike of one character directly on top of another.
-
- Next you'll be asked to specify the port to which your printer is connected. In almost all cases it will be either
- LPT1: (for parallel printers) or COM1: (for serial printers). We've included other choices for emergencies. If you
- select either of the COM ports, you'll also be asked for the baud rate and data characteristics (parity, stop bits, word
- length) your printer needs. CHECK THE PRINTER'S MANUAL FOR THIS INFORMATION.
-
- The emulation section follows and notice that we are looking for only seven possible emulations. Select the one
- that applies to your printer or press ESC if none apply.
-
- There's a brief rest as you're asked to verify the port, data characteristics (if applicable) and emulation you've
- just entered.
-
- Make sure you're printer is turned on, on line, filled to the brim with paper and that the paper is set to top of
- form. You're about to enter the wonderful world of printing.
-
- If you've entered features codes, that's what you'll print first. As the on-screen directions imply, you can skip
- the features test by pressing ESC (REMEMBER - DON'T DO FEATURES FOR A POSTSCRIPT PRINTER!!!!!).
-
- Next is the emualtion print. The emulation file you've selected is printed three times (quite noisey on dot matrix
- printers). You're then given a chance to select a new emulation to try. DO ALL THAT APPLY, but don't waste you're
- time. If the manual is unclear as to which other printers your printer can emulate, call the manufacturer. The results
- of this test should give you a good idea of the true emulation characteristics as well as demonstrate how the printer
- handles varying print densities.
-
- The next test is a humdinger (for those of you too young to know what that means, it's the equivalent of walking up
- to Sean Penn with a camera in your hands). If you're using a wide-carriage printer, it's important to have wide paper
- in it at this point. You'll just need to redo the test if you don't. Use the output from this test to determine top to
- bottom and side to side printing margins as well as to calculate the number of lines per page and characters per line.
-
- Now comes more work. Many printers have a variety of built-in fonts (NOT DOWNLOADABLE or CARTRIDGE additions).
- Here's your chance to show the world how well your printer does. Remember, fonts are not alterations in existing font
- sizes, but actual different fonts (Courier 12 point is a variation on Courier, Times Roman would be a different font.)
- Enter the codes here as you would for the features test earlier. For reasons of sanity, we've limited you to 20 font
- selections. If there are more, go back and re-do them by bypassing the other sections of the test.
-
- The speed test is a a separate test once you exit PRBENCH. It was constructed that way as it serves two purposes.
- First, the speed test tells you how fast the printer is working (naturally), but it also gives you an environment in
- which you can do the dreaded sound test.
-
- If you have a wide carriage printer, you'll perform this test at least twice but possibly six times. Once for
- narrow paper and once for wide paper in the default font. Then once for in each variety for as many fonts as the
- printer contains (remember, default fonts aren't always the draft fonts).
