PQ-8P, PQ-8S

5.13 HP Line Printer

The HP Line Printer protocol allows printing of dot-matrix output on a PCL laser printer. When selecting the HP Line Printer protocol, the PQ-8 emulates an IBM 5224-1 line printer. Other IBM printers cannot be emulated.

The HP Line Printer protocol automatically prints all output in COR mode. However, portrait or landscape print orientation with the requested font is also possible. In addition, the PQ-8 offers the choice between compressed (default) and true LPI (useful when printing on pre-printed forms). When driving the attached laser printer with the HP Line Printer protocol, reports can be printed at high print speeds and with superior print quality.

EMULATIONS

The PQ-8 offers the following IBM matrix-printer emulations in addition to the IBM 4214 emulation that is used as the default for most of the output protocols:

IBM 5224 Model 1

IBM 5225 Model 1

IBM 5256 Model 3

These IBM matrix-printer emulations can be selected through Host/PC download command 24 or through the setup software. The PQ- 8 allows access to all the capabilities of the emulated IBM printer.

The IBM 4214 printer offers 5, 10, 12, 15, 16.7, and 20 CPI; 3, 4, 6, and 8 LPI; and print qualities of draft, fast draft, or NLQ.

The IBM 5224 and 5225 printers offer 10 and 15 CPI; 6 and 8 LPI; and only a draft print quality. The IBM 5256 printer only offers 10 CPI printing. These printer emulations are often used when connecting a specialty printer, such as a barcode printer, to an IBM host.

The PQ-8 offers the following output protocols for matrix and specialty printers:

IBM PPDS

IBM Proprinter® 4201/4202 Epson®, 9 pin (FX, DFX) Epson, 9 pin (DFX+) Epson, 24 pin (LQ) Generic

5.14.2CHARACTER SET

By default, the PQ-8 uses the CP 850 character set. You also have the option to select the CP 437 character set, which is often used in PC applications. Please be aware that CP 437 has 41 fewer characters than CP 850.
