Printer setup

This program uses TrueType fonts to display information in each window. When you print these windows, you need to make sure that the Print TrueType fonts as Graphics option is enabled under the Printer Setup options. Options vary for various printers and their corresponding printer drivers, but most printer drivers either have this option or (less commonly) print TrueType fonts as graphics all the time. If this option is not selected, the printer will probably pick one of its built-in fonts, causing the printout to look different from what is displayed on the screen. 

The last item in the menu bar is (Output), which contains the selections (Setup Printer), (Setup Print Job), (Print Graph and Main Results), (Print Table of Detailed Results), and (Copy to Clipboard). 

Elements from Spectrum Window to be plotted Printer Setup... 

Clicking this button opens the Printer Setup dialog box through which the user can select the output device from a list of all devices known to the MS-WINDOWS operating environment. 

Adjust the vertical scale and the vertical offset for the main trace spectrum to obtain the best display of the signals for the ring protons. Click on the File Param. button and set the plot limits to 6.0 ppm and 3.5 ppm. Click on both the F1/F2 for all and the Y for all buttons to transfer the plotting information from the reference spectrum to the other six spectra. Click on the OK button to close the dialog box. Do not click on the Return button as this will lose all the Separate Plot plotting parameters that have just been set. From the Output pull-down menu choose the Page Layout option and select the same parameters, options, colors, fonts and the printer setup as used in the multiple display above. Use the Preview option for a final inspection before plotting this Separate Plot layout. 

To start the printout operation the Print... option in the Output pull-down menu is used. If there is more than one window on the screen choosing the Print... option - and using the mouse - allows you to specify the window which should be plotted. If all windows should be plotted, use the Print all option. With Printer Setup... a variety of output device specific parameters defining the resolution, the paper size and other printer variables, may be set. 

You ve set up a network printer. However, you cannot print from your DOS-based programs. What did you do wrong during printer setup ... 

Once you get the desired graph on the screen, you probably want to make a hard copy. To print, hit the SPACE key to bring up the graph customization dialog box shown above. Notice the "Print" and "Printer Setup" items on the bottom line of the dialog. To print, you move the cursor over the "Print" item and hit the ENTER key. ChemSep will send the graph to the printer identified by the "Printer Setup" menu. 

To get the graphs into this document, I instructed ChemSep to write a Windows bitmap into a file which I later imported into MS Word. I edited the "Printer Setup" (by moving the cursor over this item and hitting ENTER) to read as follows ... 

Over 100 variables have been identified that affect the screen-printing process, ranging from the paste properties to the printer setup to the screen properties. Only a few of these are witiiin the control of the process engineer. Adjustments in tiiese parameters can compensate for most of the remainder. 

In the off-contact printing process, tiiis is arguably the most important parameter in the screen printer setup. If it is too large, the screen will rapidly lose tension and the print will lose definition. If it is too small, the tension on the screen during the print will not be sufficient to transfer the paste to the substrate. Referring to Figure 5.19, the magnitude of snap-off is dependent on the size of the screen, with a ratio of maximum screen dimension to snap-off of 200 1. A list of typical snap-off distances for a sample of standard-size screens is shown in Table 5.3. 

Successful screen printing begins with a stable printer setup that comprises the following ... 

Substitution of Eqs. (8.64) and (8.65) into Eq. (8.66) yields the relationship between the screen printer setup and the newtonian ink viscosity to fill the screen mesh ... 

The process parameters key to the stencil printing process include the squeegee type and hardness, print speed, print pressure, and print gap. An optimal stencil printer setup provides a clean sweep on the stencil surface and a repeatable solder paste deposition process. Shore A scale polyurethane squeegee hardness level between 85 to 95 is appropriate to achieve repeatable solder deposits for lead-free solder pastes. Print parameters such as the print speed, print pressure, and the print gap are adjusted to accommodate the variety of solder paste rheologies available. There are no specific equipment modifications necessary to stencil printer lead-free solder pastes.
