[. . . ] EPSON ® P-80 PORTABLE PRINTER User's Manual FCC COMPLIANCE STATEMENT FOR AMERICAN USERS This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Subpart J of part 15 of FCC Rules, which are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient the receiving antenna - Relocate the computer with respect to the receiver - Plug the computer into a different outlet so that the computer and receiver are on different branch circuits. [. . . ] Overlapping dots Print Pitches There are two print pitches (or widths) available on the P-80. Pica is a standard character width used on typewriters and prints 10 characters per inch. Compressed pitch prints 34 just over 17 characters per inch. The smaller characters allow for spreadsheets, or other work that requires compact printing, to be squeezed on an 8½-inch page. In Figure 5-3, you can see the difference in the two pitches. Pica is the default, the pitch in effect when the printer is turned on.

Comparison between print pitches Pitch Mode Combinations Expanded is a print mode that can be used with either Pica or Compressed print pitches. You can add this mode to your program to printout for one line only or for longer passages. Expanded can also be used with most of the other modes. Expanded mode Expanded mode doubles the width of the current pitch mode. It does this by printing twice as many dots, twice as wide, as you can see in Figure 5-4. Pica A Expanded A Figure 5-4. Pica and Expanded letters 35 Print Quality Modes There are two modes that produce boldface (darker) characters which make your printout more distinctive. These modes are DoubleStrike and Emphasized. Each gets its bold effect by printing overlapping dots as explained earlier in this chapter. Figure 5-5 shows the difference between Single-Strike (the default), and Emphasized. On the P-80, Double-Strike and Emphasized produce the same result. Double-Strike may produce a slightly different result when printed through your software. Figure 5-5. Print quality differences Dress-up Modes There are two more modes you can mix with any of the other modes to give your printouts a finished touch-Italic and Underline. Italic characters are printed in a typeface completely different from the more usual Roman characters. Any computer system can select Italic mode without software adjustments. The P-80 has a built-in Underline mode making it easy for you to underline anything. You can underline characters or blank spaces as demonstrated in Chapter 4. Mode Conflicts and Priorities Print modes have an order of priority; some modes are assigned greater value than others. Also, certain modes can be combined and others cannot.
