Page of GC20-i807-7 As Updated April 1, 1981 by TNL GN25-0829 The buffer imaqe is 5 representations of a 48-character string containing: • The alphabetic characters • The numeric diqits, twice • The special characters: * and / since the line length for the print verification is not specified on the uccccw macro, it defaults to 48 characters per line for 5 lines. Insert the following code in DMKUCC: UCC NUM1 DC 24CL'1234567890' UCCCCW NUM1,(60,60,60,60) The NUM1 print buffer consists of twenty-four 10-character entries. If, after DMKUCC is reloaded, the command LOADBUF OOE UCS NUM1 VER is specified, 4 lines of 60 characters (the la-character string repeated 6 times) are printed to verify the buffer load). Part 2.

Page of GC20-1807-7 As Updated April 1, 1981 by TNL GN25-0829 IBM 3800 Pri nting Subsystem The IBM 3800 printinq Subsystem is a high-speed, nonimpact printer that combines electrophotographic and laser technology. The 3800 printer can achieve speeds of up to 20,040 lines/minute, while several unique features give the user the ability to control the characteristics of printed output. The features of the 3800 printer include: • Forms control buffer -controls the amount of vertical space between printed lines. The user can specify vertical spacing of 6, 8, or 12 lines/inch. • Multiple copy printing -allows the user to request multiple copies without the use of carbon paper. The 3800 uses its hiqh speed to repeat-print the specified number of oriqinals. • Copy modification -allows the user to print or suppress predefined information on specified copies of a page. For example, a different name and address can be printed on each copy of a page. • Forms overlay -allows printed (flashed) from inside the form. the user to specify a forA or grid to be a negative while output is being printed • Character arranqement tables -allow the user to specify predefined character set will be used to print a data set. character set contains up to 64 printable characters. which Each • Character modification -allows character sets to be modified or extended to meet the user's needs. For detailed information on the 3800 printinq Subsystem see: lng printing !!§ • Qi lh§ 180Q printing • ££inling • fQ£ the 180Q R£inting VM/370 supports the 3800 printer both as a dedicated device and as a real spoolinq device. Using the 3800 Printer as a Dedicated Device VM/370 allows a virtual machine that is configured to support a real 3800 to attach the 3800 for that machine's exclusive use. When used as a dedicated device, VM/370 supports all of the facilities of the 3800. 226 System Guide
