1.1 FEATURES
/'
The LQ-570+ is a small, light-weight, low-cost, printer with advanced paper handling that is upper corrmatible with
the LQ-510/550 and compatible with the LQ-570/1070. The printets main features areas folbws:
1. Use of ESC/P 2 control codes
Ability to print multi-point fonts
Ability to receive and print raster graphic images
Compatibility with the LCVSQ series available on the market
2. Printing speeds: 225 characters per second (cps) (draft, 10 characters per inch (cpi))
High speed drafl has not equiped
269 cps (draft, 12 cpi)
225 cps (draft, 10 cpi)
90 cps (LQ, 12 cpi)
75 cps (LQ, 10 cpi)
3. Optional interface card
4. Clear, easy-to-read printing with standard EPSON fonts
5. Multiple fonts resident in the printer
9 LQ fonts (Roman, Saris Serif, Courier, Prestige, Script, OCR-B, Script C, Orator, Orator-S)
1 draft font
6. Control panel switch selection of fonts, mndensed, and cut-sheet feeder (CSF) bin
7. Optional tractor unit that can make up push-pull tractor
8. Easy handling of cut sheets with the optional cut-sheet feeder
9. Continuous Paper
Three ways to `insert continuous paper (front/bottom/rear path)
Auto backout & auto loading (rear insertion)
Continuous paper can be used without removing CSF
Standard tractor unit can be attached in two position (pusWpull)
Cut Sheet
Two ways to insert cut sheets (front/top)
Auto loading
The LQ-570+ is equipped with the standard EPSON 8-bit parallel interface( Printing is not possible for the following
baud rates: 1800, 200, 134.5, 110, 75 bps). Various interface options ensure mmpatibility with a wide variety of
computers. Table 1-1 lists the interface options, Table 1-2 lists the optional units available for the LQ-570+, and
Figure 1-1 shows an exterior view of the LQ-570+.
