PQ-8P, PQ-8S

Although the PQ-8 artificially produces these missing characters, at times the “reproduction” may not satisfy your quality requirements.

5.14.3PRINT QUALITY

The PQ-8’s IBM 4214 printer emulation offers Draft, NLQ (Near Letter Quality), or Default print quality for print-quality options. If a default-print-quality command is sent from the host, the interface allows you to specify whether this default is Draft or NLQ. Set the desired default print quality through Host/PC download command 22 or through the setup software.

If the printer has the capability, the PQ-8 allows you to further specify if Draft printing should be Fast Draft or Normal Draft (Host/PC download command 23). Request for Draft printing can come directly from the host or from the PQ-8 (host sends Default print quality and PQ-8’s 4214 Default Print Quality is set to Draft). If the printer only offers one draft printing mode, the setting of the Draft Printing option is ignored.

Another way to modify the print quality is to set the printer to a certain value through its front panel. When you activate the Override Format Commands option of the interface through Host/PC download command 16 or through the setup software, the printer’s front panel settings are “locked in” and remain valid until the Override Format Command is disabled.

5.14.4PITCH CONTROL

The PQ-8’s 4214 emulation permits the printer to print 5, 10, 12, 15, 17.1 and 20 CPI (pitch). The pitch can vary, depending on the CPI selected in the host document or the printer’s front panel.

The 5224/5225 emulation only allows 10 and 15 CPI printing, and the 5256 emulation only allows 10 CPI printing, unless the CPI is overridden at the printer’s front panel.

5.14.5GRAPHICS PRINTING

The PQ-8 will print the same Advanced Printer Functions (APF) and Business Graphics Utility (BGU) graphics as the IBM 4214, 5224, and 5225 printers using All Points Available (APA) bit-image graphics. This method is for printing continuous patterns such as bar codes and logos that come from the twinax host. This is the method of graphic printing that IBM used before IPDS was developed.

Graphics are printed on IBM System/34, /36, /38 from the APF and BGU programs and programmer-defined characters using the command Load Alternate Character (LAC).

This capability is supported by 5224, 5225 printers in spacing of 10 and 15 CPI and 4214 printers in spacing of 10, 12, and 15 CPI.
